Disappointed with Service and Lack of Support

I visited the Teekie Town store at Red Mall today to make a payment and enquire about my account. I am extremely disappointed with the service I received. Firstly, my credit facilities were blocked on the account, and I was told that I failed security questions. However, I did not make any call to them, so I am unsure which security questions were failed or how this happened. I then requested the staff to check the last payment on the system, but the consultant advised that she was unable to assist with this. I also asked to speak to the call centre, but I was told that they do not have a call centre available. This experience was frustrating and unhelpful. It is concerning that basic account enquiries cannot be handled, and that there is no clear support available to assist customers.
