Worst Provider ever

My account was deducted twice from 2018. No one bothered to fix this. After I have several reference numbers and complaints. I have been fighting this for years. My phone gets cut off every month because it shows I have an outstanding payment. I pay my account religiously every single month on the 29th. I then have to go into a store, fight with the person on the other side of the counter. I had the pleasure of working with a Maria, which did not help me at all even after I explained the issue. Sent Bank statements and proof of payments of the account which was paid and I was ignored. I had to then go through other channels to get my phone activated again. This took 2 days where I did not have a phone. MTN is literally the worst.
