Poor Service from MTN

On 25 November, MTN debited the usual amount from my account. On 26 November, I manually paid the outstanding amount that I missed for the October invoice. On 29 November around midday, they decided to cut my services due to "returned debit order". I have proof that I made the payments already but they are adement that I did not pay.

This is why MTN is known as the Most Terrible Network.
