Do not risk requesting a charge back, a guildie of ours had an issue with their bank and SE check out where it charged them multiple times, and he called his bank to cancel the payments since they were still processing bank did not do that they waited for them to post and just issued a charge back. He tried to explain the situation and have either the items revoked from his account or if he could rebuy the items. I was going to give him my card so he could pay the chargeback back so to speak. SE customer service while understandable had their tied.
