Mtn not costumer friendly.

I have been a mtn customer for 10 years. Same number same banking details. Got a new contract and never been debit. Didnt bother as this was happening every month. For 4 months o didnt check and enquire this. Mtn said it was their mistake and i can do manual payments as i do not get my salary due to covid. Today i was suspended due to my account. Very upset as mtn never told me i would be cut off. And had to pay 900 rand to activate my line. This will be my last contract with mtn as well as my wife. Long partnership with mtn down the toilet
