Cut off by the Call centre!

I received my statement and believe my instalment was calculated incorrectly - R660 per month, on a 12 month account. When I called the call centre a guy took the call and indicated he could see something was done to correct the instalment and he'd get back to me, he promptly put me on hold for a long time then cut the call. This might sound like a small complaint, but honestly I am extremely busy! And for me to make that call, be put on hold then get cutoff is a huge waste of my time. This is not acceptable service! Where is the client service in calling me back when you have perhaps accidentally cut the call (it was most likely deliberate as it was not a standard query).

I need my correct instalment emailed to me asap!

Thanks Clinton
