Ever had your account cancelled because of chip dumping?

[Mercyful]

This is my problem. A friend owed me $30 and the only way he could pay me was through Party Poker.

So he transferred $50 to my account and then we sat down on a table (heads up) and I gave him back $20.

After that we played together at a Omaha table for like 1 hour, but we didn't do any team work at all.

I just woke up and I can't log in to Party Poker, I got a message my account was cancelled.

What can I do in this situation? What should I tell them?

I don't want to lose my money, and we didn't do any team work.
