Barclays Credit Card Complaint

Barclays Credit card department,

Credit line increase/decrease Tennessee

I had a credit limit of $3000.00 on a Barclay Visa card. I co-signed on an auto rental with a temp subcontractor for a one-week term. After 2 weeks I received a call from the auto rental reminding me the auto was due in. The person that had the auto assured me that after the first week, he would return. I could not make contact and when I received call from rental agency at end of week three, I suggested that it should be reported as stolen as I could make no contact. That was in - 2015. With no charges from the auto rental until - -, there were - charges added to my card which put me over the credit limit, imposed by the issuer, a - dollars. I called Barclay 's help line and was told the credit limit was not enforceable. Then I requested that a hold be put on my account, thinking that would prevent any more charges. Then on - -, there were - other charges from the auto rental for some $3200.00 which then exceeded the credit limit by some $ 4,000+. I was more than shocked and called their help line and was told that a hold would only stop the card working if it was swiped, but would not stop other charges coming thru their system. I then cancelled the card. I sent a fax and - letter to Barclaycard to file a dispute on - -. On - - I was sent a letter in response that indicated they could not further pursue because they tried to call me twice on - -. There is no record on my cell phone of any call attempts from them. The letter was generic with NO NAME or contact number or email other than their Service Center # that could do nothing to assist me.
