StubHub Stubhub Seller beware! San Francisco California

I had sold a pair of tickets for $171 through Stubhub for the Trans Siberian Orchester at the Giant Center in Hersey PA in December. Three days after the event I get emails stating that the buyer was denied entry and my credit card was being charged the orignal selling price plus $104.50 selling error. 

I contacted the Giant center for the barcode reports and was told that the report only shows the accepted and denied times.  This is what Stubhub asked for and this only proves that the buyer was denied.  There is nothing to prove the seller, me, did nothing wrong. 

I know I did nothing wrong other than selling through Stuhub, but I do not know what happened after I sold them.  Either the buyer allowed to be duplicated (were they hacked) or they gained valid entry and then proceded to get a re-entry ticket (for smokers) and try to have the tickets re-scanned to show denied entry.  The timing on the scan shows it could have been done. 

I provided everything they asked for, only to be told and charged that I was at fault. This was the first time I ever sold tickets on line and will not do it again. I also will not buying from Stubhun also. 

Just an FYI, they will supply a phone number to call "your" representive that is in charge of your case in the email, but they never answer and never call back when a meesage is left. 

Stubhub may protect the buyer but never the seller.
