I can walk away from situation my account get ban and never look back but not my money especially when they resist to give my money back, I think a Red Flags for this situation if I can't get it back.
If you move the topic to
scam accusations board then you will get more attention. You will also need clear unaltered evidences to back up your claim as it's hard to believe something which are just words, no offence.
Rest assure, I think if there are no cheating from you then it will be just a misunderstanding and with proper addressing you can relove it.
