Barclays PLC Credit Card Complaint

Barclays PLC Credit card department,

Transaction issue Arizona

I returned merchandise to the - - for a refund over 30 days ago. I still have not received a full refund and when you check the credit card statements, you can see where the credit was applied to the account and then taken back on the same day. There are about - cherges that have not received a matching refund from -/-/- to the present. I have reported this to Merchant Disputes but I still can not get any solid answers as to what is going on. I am trying to determine if the credits on my account are : 1 ) correctly reported from - and 2 ) if the credits that were taken away from me were taken away by - or my credit card comany as a re-billing for fraudulent reasons.
