DISGUSTING SERVICE FROM MTN AND MTN BLUFF

Opened an account in July at MTN Bluff. The app does not work to show the data usage. For most of September to date, there is no connectivity. I tried phoning MTN on 083135 and 135 but no response. To check data balances, the sim must be taken out of the wifi device and put into a cell. What nonsense is this? Then for most of the month, there is no connectivity yet my account will be debited and I pay for a service that was not provided. This is not on. I intend reporting this matter to ICASA. Emails sent to the store where this account was opened also do not respond. The service is damn pathetic.
