still no response from African Bank

I wrote a report last week complaining about African Bank, they tried calling me back once and sent an e-mail to me to say they tried to reach me. ReallY!!! I responded to the e-mail advising that I missed their call, I also attempted to call them back and held on for 25 minutes, no one answered the phone!!!!!....To date no response. I will not pay for the damaged lounge suite as of end of June. You are more than welcome to collect this *******!!! I will now take this matter further.
