Deceptive practices and unauthorized…

Deceptive practices and unauthorized negative balance
"This service is highly deceptive. They claim to be a virtual card provider, but when my balance was ZERO, they allowed a merchant to charge my account and forced it into a NEGATIVE balance without my consent. When I confronted them, they contradicted themselves—first saying they aren't 'prepaid,' then saying they 'don't provide credit.' They basically force unauthorized loans on users. Beware! Their 'forced collection' model is a trap for customers. Customer support is useless and refuses to fix their system failures."

Took money, no order

So disappointed. I ordered my second pair of straps from Karta - eta 6th - 11th Sep. Despite emailing twice and receiving no reply, no order has been received. Don't even do much as offer tracking for the order as a privacy error comes up. Order #6061, if you read your reviews more than your customer emails - could you look into this?

Very poor customer service

Bought a bottle for my son’s birthday but arrived in dented / ripped box as if it had been dropped. Have constantly emailed customer service, tried live chat and messaged via Facebook and zero reply. Really disappointed as this is a present

Awful Company - Avoid!

Awful customer service. Ordered a bottle on the 24th Jan, website says it was dispatched. Given a Royal Mail tracking number that has been sat at "unable to find this item" for nearly 3 weeks. Have tried emailing, live chat on their website and Facebook message only to be completely ignored. Still no bottle and obviously company have kept the money. Avoid at all costs!

Update 10/2: bottle has arrived finally, but upon opening the package, the bottle has a big dent in the side, the lip of the bottle is all scuffed and the lid is wonky when screwed on. Terrible manufacturing and clearly made cheaply in a hurry. No doubt Karta will now ignore all further emails and attempts to return like they've ignored all emails so far!

Poor customer service

Bought the bottle for my husband as a Christmas gift. When he opened the box, the bottle had a dent in it. Tried to return to exchange but website wouldn’t let me due to having purchased it a few weeks earlier. Sent a form on their website with photos but heard nothing back. Useless customer service. Bottles unstable, may be due to the dent but appears I’ve paid nearly £50 for a gimmick that’s now just like any £2 water bottle.

My second order from Karta!

My second order from Karta! Such an amazing product (even if it does bring a lot of attention 👀)! My gym ended up scrapping their bar Jack so my new bottle fits the job perfectly! Decided to buy a secondary bottle as a gift! I had to talk to customer services regarding a slight issue, this was corrected within minutes of sending my email, and was dealt with far better than I’d have imagined! Amazing product and Amazing customer service (thanks again Pete!)

Hidden fees

I bought a bottle to be shipped to Spain. No mention of paying extra import duties at checkout but when it arrived I had to pay another €18, bringing the total to €75. Not worth it.

bottle is great

bottle is great! However, it could benefit from a wider base for more unstable surfaces (or an add on component that's wider)

You actually sent me two. I only ordered one. I sent a message right after I received it and wanted to know what I needed to do about the extra one.

My grandson loves it !!

Hi Belinda - great to hear your grandson loves it! I believe the second one was sent because the first was deemed lost in the post and then appeared, don't worry about returning it, your grandson can give it to one of his friends or keep it as a spare

Thanks for your order!

Excellent quality

Excellent quality. Remarkable how cold it keeps drinks. The sports lid is a must when buying the Karta bottle. I never have to struggle again putting weights on the bar, but most importantly taking them off. Class product, can’t wait for more colours

Hi Tjero, thanks for your order! Unfortunately, as we only ship from the UK and US, customers from any other countries are required to pay customs fees as detailed in our shipping terms - we're setting up a distribution centre in the EU this year which will help but as our organic content is served everywhere, offering free shipping to the EU is the best we can do at the moment to service this demand - Pete

You need one!

Great! So good for loading/de-loading barbell hip thrusts or deadlifts. I can worry less about my dodgy back! And it's a real conversation-starter too!
