Mtn and the Putrid service

Been with MTN for 10years, I have tried to upgrade my contract for a new device and received such terrible assistance in store as well as online and received no help in getting my upgrade done.

They have refused to take the necessary steps to increase my credit my credit limit yet they have my whole contract history from 2016.

I am disgusted and beyond disappointed in how MTN treats loyal clients I have even informed them that a competitor is willing to do my deal for me and they showed absolutely no interest in assisting me still.
