Shell credit card informs me that I have an unpaid charge from XXXX XXXX 2015 on XXXX XXXX of 2015. Talked to a XXXX in Tennessee at XXXX Mountain time on XXXX XXXX, told me that there was no record of this charge. I thought that it was a scam and put it aside for the time being. Received XXXX bill and had a charge on it for {$30.00} ( XXXX XXXX, 2015 ). Called Shell and asked that this charge be disputed and asked that they send me proof of this charge. Shell agreed. Tried to use card on the XXXX of XXXX and was denied. Called Shell the XXXX of XXXX and was told since I did not pay my bill on the XXXX of XXXX that card could not be used. Essentially denying me use of the card because of a charge that was, what I thought, in dispute.
