troubles with gunbroker

I was going to post on gunbroker but I got a message that my credit card was unauthorized So I re-posted the credit card info and it came back denied wrong billing address. I contacted GB through the help line and I was told my credit card company was not accepting the $1 payment. I called the credit company and they told me that my $1 was authorized by them and the problem was on GBs end. While they were on the phone I put my info on the GB site again and the credit card person told me it came through approved. but the GB screen said denied. So the credit card company gave me a number for GB I tried the GB number but all a Got was a recording that cut me off. I tried contacting them through the help option but I kept getting the same stock answer in correct billing address. also every time I tried to post my credit card with them I got a email from GB saying that the $1 was approved. I do not know what to do it is impossible to call GB with out being cut off by the recording and I tried the help line but I just keep getting the same stock answer. I guess I will have to take my business to auction arms
