You’re not just entitled to a refund just because you want one, there’s a process to go through it and ignored it….
They wanted to know if the fault lied on their end or your end, one of them they would be liable to refund you, the other is actually on you.
So no, you require tech support BEFORE demanding a refund in almost all cases.
You’re just an entitled prick apparently.
They asked for logs, gave you a reason for why. You claimed you already did, even though they explicitly told you why and to not edit them. You were also the only one with this issue, that’s not likely something on their end, which wouldn’t be eligible for a refund.
Again, they are an ass, but look in the mirror, your obstinance didn’t help.
