MTN - Bad service

Poor service almost from day one. 1. Charged for insurance after specifically stating I have my own insurance. Still struggling to get it cancelled and refunded after almost a month. 2. Specifically asked for a debit order date of the 25th of each month, come 7 January, MTN tries to debit my account. 3. Received payment link from MTN on the 7th and paid account via the link on the 7th. Woke up this morning to a suspended service. 4. Don't receive SMS from a number of service providers, still struggling to have that issue resolved.
