CounterBoosting 

Very quickly raised the rating, got the rank global

Unproffesional customer service, and very unreliable. If something goes wrong with the boosting they will just ignore you. No refund will be issued.
PS: Dont try to deny it, you know who I am.its still not too late to make up for yourself

They are capable of getting multiple rank-ups done in a day.
BUT its been well over a month since my purchase and we've only done 2 sessions (about 2 ranks each). There is never a specific time they are online and if i didn't happen to be at my PC im sure i would've missed them actually boosting- a very rare occasion.

This all wouldn't be so bad if they actually took time to reply to messages on top of that. Been about 2 weeks since last reply..

It's been 28 days since my order. I wanted to go from s4 to gn1. I ordered it and DIDNT order the duo lobby game thing. They said they didnt have solo boosting at the moment but I could lobby with them and boost. I played 2 games, and since then its been silent. Its been 28 days and im not nova1 yet. Big scam, its disappointing

it has been two days and still nothing. Two stars because I still have hope but that's it.

Edit 1: 3 days now and still nothing.

Edit 2: 4 days now, nothing. I’m contacting them via email.

Edit 3: they responded quickly and started the boost (already 2+ ranks). I recommend contacting them via email if nothing's happening.

Edit 4: I got overwatch banned for 1 month. Do not use this service or any other service that uses the "vertigo boost" technique as it will get you banned.

A little slow to start the games, took about a day, but after starting, the process is very quick, and only takes a few hours for one rank.

fast & good :)

Takes a while to get started but once they so the boosting process is fairly quick, good customer service would recommend this for boosting, will be using their services again. The whole process took about 8-9 days.

Very fast and good Service, +++
I will use it often now

Really good and fast service good customer support and good service in discord

Paid 7 hours ago still not logged into my account, nor have they contacted me. I’ll edit the post once they contact me or have logged in
Edit : Been 24+ hours now no contact and no login.
Edit : they have just added me on discordant
Edit : good service once done, slow start. Friendly and did apologise about my wait and ensure it won’t happen again.

Took a bit to get contacted but after that boosted in about 4 days as my and theirs timezones were different so they had to manage to get me boosted early now that is superb...They are indeed the best boosters!

Most reviews say their boost was completed in 24 hours but its been over 3 days since I first paid and I still haven't even gotten any notifications or response through discord, steam, or email. Not sure what the deal is but I'm still waiting for my orders.

Edit: They contacted me 2 minutes after posting this review and apparently it was an accident on their end. I guess my order just got forgotten. They told me they would do it the next day yet I've just been ignored for the past 22 hours. It's now nearing the time yesterday that they claimed it was too late for any services so I guess they only operate within a 2 hour window each day? I've literally messaged them 5 times throughout the day while they were on and got no response. I don't know if I'm an anomaly or what but I cannot recommend anyone to this service because it looks like there's no guarantee they won't just take your money and ignore you.

Edit: They just finished my order so in all, it took about 12 days. 3 of those days I was busy and was unavailable so those were completely on me. The boost itself is crazy fast and efficient and it's a great service. I guess I just got unlucky with the order and the timings.

Took i while to get contacted, turned out I sent a wrong discord-id lol. Got boosted within an hour afterwards :-)

Good Service, Nice People, Kinda Slow. Took a day to first be contacted, and some of their bots were banned during my boost, but it still went well and I got to my desired rank in about 3 days.

Excellent boosting service, professional and seamless, completed with ease!

Fast and Easy Communication, Would use again!

Good Guys , i want thx you

Best boosting service! Legit , fast, secure! Thanks guys!
