Customer service

I have an account with Absa and app**** for a credit card. After many promises that they would get back to me within days, i received no response. When i went into the bank they required additional info which i submitted and they would contact me. It's been a month and still no response !! After making three calls to the branch, they said they would contact me, but no surprise - NOBODY called. I am aware that it could be the systems fault but that does not excuse the fact that a quick return call to let me know is the decent thing to do. The customer service is APPALLING !!
