Non-service from Standard Bank

Every time I try and pay for an air ticket on line, standard bank thinks it is ***** and blocks my card. I then phgome standard bank. 1) First attempt: waited 20 minutes in the queue. Spoke to a consultant, who put me on hold. Waited anoter 15 minutes, the hung up and trie3d again. 2) Second attempt. Waited another 22 minutes in the queue, the ran out of airtime. My fault, not theirs. 3) Third attempt: Loaded more airtime, waited another 25 minutes in the queue, then the phone went dead. This is a bank that has no committment to service!
