MTN you have disappointed

Hello All, I am not one to complain. I have never posted anything on Hello Peter or any other platform before. But I am at my wits end. I have been trying for close on a year to cancel a simple data package with MTN. In fact I don't even know what it is used for. The customer care email is beyond useless and totally ineffective. You never have a string of mails with the same correspondent and literally need to start from scratch each time. the 135 number is also painfully inefficient. It seems to me there is a type of modus operandi, the back and forth, the slow response just results in another months fees being charged with not been any closer to the solution. Surely it cannot be that difficult in this day and age to close a simple data account and move on.
