Highly disappointing service

I'm so disappointed. On the 3rd of May I called the customer service and informed them that I have been ****med. The advisor I spoke to told me that they will send me an email with a form that I should fill in. I did that within a few hours and did not receive any response or reference number. This went on for a couple of days and eventually I decided to go to the bank, when I got there I was told I should call the customer service to follow up. I did that and recieved the reference number and was informed that I will get feedback within 10 working days. I was fine with that but then after some time, I was then told that I sent this to the incorrect department. Why was I not told this the first time or the second time. I was told to await a call from the relevant department. I waited and waited but nothing happened. I then sent an email but received no response. I had to chase and call them and only then was I told that this has never been logged on the system. So many weeks have passed and my case is only being logged now. Even after logging that case, I was informed that I'll receive my reference number shortly but I am still yet to receive that.
