Unsatisfactory Service to me, the customer of Discovery Bank

I have had a fixed deposit with Discovery Bank for one year and wanted to speak to treasury in order to discuss further investing. I phoned and was told I would receive a response within 24 hours. This happened on two occasions yet I heard nothing. I phoned again and after speaking to a lady was put on hold, waiting for treasury. After half an hour I gave up. Then I phoned again and received no response and on a further occasion was cut off. In the end I phoned three further times, either to be cut off again or to be told that I had to phone Treasury directly. When I was given the number and I phoned, it was impossible to get through on the number. After discussing this with various bank employees, the eventual outcome after many hours of my time , after asking for assistance from a previous bank manager left me with the cer*****y frustration left me feeling particularly annoyed at this inefficient lack of customer care. The lack of customer service is appalling and unacceptable.

I had every intention of reinvesting but this has left me with a particularly sour taste in my mouth. I would like a response. I wanted to report this to H Calner directly but I am unable to access the appropriate channels to get this to the top. Something needs to change for the good.
