Paypal chargeback question

[TurboDuGetto]

Can anyone help me out. I play a game called runescape i have lot of gold on it that i sold to a company that buy and sell. i sold over 1000m to them thats like 1000 dollar. So my question is can they chargeback or no? i didnt sell in one go only per 100 dollar so they send me the money 10 time to the same email.

can you prove online viewable tracking showing it has beedn delivered to his paypal address via a commercial carrier?

chargeback is with cc issuer,each chargeback would cost you $20 if you lose,so you could lose $200 just in fee alone.
