So I cancelled my viveport account, I’m not sure, like 2-3 months ago. And then today noticed that they had just charged me again! So I contact support, and oh, they can’t refund me unless I somehow have a screenshot of the cancellation screen of my refund.
That’s total BS, I’m going to do a chargeback via my Visa, but I’d really recommend everyone be really careful with Viveport. Pretty shady and I won’t trust them in the future. See relevant post about refunds as brand loyalty.
