Customer service falls through the cracks

I tried to do an internet transaction 2 nights ago and got a message that my card had been deactivated. I went into the Beacon Bay (East London) branch and spoke to Zola. He tried different options to resolve my query, but could not because it was a national problem. He asked me to return in 1hr to give time to resolve the problem. I did this and the problem persisted. He said he'd keep me in the loop as he was only leaving the bank at 6pm and would call me to come in and sign off. I've to heard from him nor the bank. In the meantime, I urgently need to do the payment which is time sensitive. Can someone urgently give me feedback and find a solution to the problem.
