Disappointed

Last month MTN tried to debit double the installment saying I owe them, I knew I didn’t cause my contract is debit & in almost 10 years of being with them I’ve never missed an installment. This month they changed my debit to cash without alerting me. Then today I woke up to a realization of my phone being cut off. I then went to a branch and made payment, expecting them to reactivate my phone. I’m still without connection even now and I’ve spoken to 3 supervisors at 3 different times trying to reconnect my phone. They kept telling me it’s connected but it still isn’t. I’ve never been so frustrated and annoyed with the level of service from a company I’ve been loyal to for so long
