Horrible service

Honestly just experienced the worst moment with MTN. I got a WiFi modem with the online team, and recently changed my package after a year of using their WiFi. The first issue was I followed up 4 times (in store and via email) for them to update my bank account for the debit order to go off. Upon which I was informed it was updated when it wasn’t. I was told “this is what MTN does” and I must inconvenience myself and go in store to make payment. How does it take u 3 months to not update an account and I’m told this is what u do? Misleading!!! On top of that u did not update my account contact number and made the courier take one extra week to deliver my WiFi and I had to keep following up! Not knowing the number was wrong and had to re-do the update. Then I get billed for march when I already paid for Feb for both of them and am on a month to month contract and lost my money for the old modem due to the cancellation not being finalized. My money was wasted as I cancelled both WiFi and was told I must pay for much just to be refunded and told this is how online team works. Worst service ever. You went from a high to down low
