Please help

I was banned for sandbagging, but I don't know when, and the email just says,

Can anyone try to find where exactly I was sandbagging? The account is @EnCrossiantIsBrilliant  

Also, if anyone knows what happens to the membership if my appeal is not good enough, I would very much appreciate it if you could tell me, because if I don't get my money or account back, I basically wasted 60$ to be wrongly banned (it was during the black friday deal).

Lastly, I would also like to know how long it takes for the appeal to be reviewed and responded to.

It should just take a few days. Looking through your archive it probably was related to your long string of 2-3 move games; those appear up have been unrated though, so the that likely shouldn't have resulted in a closure

Ok, thank you guys, hopefully I will be unbanned soon.

Think about your opponents. They don't know anything about you or your problems. They came to play. But you just wasted their time.

That's wrong.
