Wasted hours of my time and never sent my hats
I backed Movi's kickstarter back in 2019, choosing a 'reward' of two hats. When the backerkit survey was available I completed it to select rewards and provide my postal address. When reward shipping wound up and I hadn't received or heard anything, I contacted Movi, initially via the kickstarter page, and received a reply incorrectly claiming that I don't fill out the backerkit survey but requesting I send them an email with my address. After I sent that email, including a copy of my backerkit responses as an attachment, they provided a tracking number, which sat in US customs for a week before eventually being delivered to an address in Canada (I'm in Australia and provided my correct address in the survey and twice per their requests in emails at this point).
When I followed up via email again, another reply indicated they'd 'try' to get some hats to me (the colours I'd selected in my survey now being sold out) and requesting my address, again. And again, nothing happened, and I never received any response to this or subsequent emails.
Having exhausted all other options, including contacting backerkit and kickstarter, I eventually disputed the transaction with my bank.
