POOR CUSTOMER SERVICE!

i am very disappointed with MTN, 2 missed payments is showing on my profile which has affected my credit score badly. I have been to a branch , ive been emailing(no response), I've been calling ,whatsapping and ALL not helpful, says alot about customer Service, for something very simple I couldn't be assisted with for 3 months.

MTN failed to take the amount when debit was due, this has gone on for 3 months now.

Can you please make contact with experian to update the "missed" payment which i did not miss as the money was in my account MTN just failed to take it and holds the client responsible.

i am just very very disappointed i work so hard to keep up a good credit score and MTN just messed it up. I have my proof.
