MTN BAD SERVICE

I'm very upset with the MTN, One of their service consultants went and changed my debit order date to the 21 of May, but it's always been on the 1st of every month. They also went and increased my monthly repayment without notifying me. This is very bad service from MTN, and I've been a client of theirs for many many years now 😣😣😣😣😡😡😡😡😡
