What does it take to get a response from Absa??

I app**** for a credit increase with Absa on the 15th Dec 17, I prepared a cover letter letter outlining my request with all the relevant support in documents attached. I was notified told I was provisionally approved. Yet after numerous emails, calls at my expense of which I have all recorded. I am still without even a response. Then I receive an sms saying documents not received application expired. Oh my sweet goodness, the lack of service and communication is just one for the record books... Uv had a credit card with you for around 6 years, and I can't even get a simple request processed.. Thank God my main bank account is with Fnb.. I will be closing my account at the end of this month.. As I don't feel like giving money to you on bank charges and interest tojust waste it on the excuse you call a credit card division. My recommendation to all, don't bother with Absa, unless you want to end up doing all the leg work and still not get a response. I have all the evidence to back up my poor experience, should this complaint reach someone who takes pride in their job.
