Mtn **********ly overcharges

I emailed a complaint to MTN on the 04 May 2020, regarding my bill, I signed a contract for a fixed amount and one of their employees had changed this and as a result my bill has inflated. This obviously means more money for MTN, I top up my contract when I run out of data and they charge me for topping up when I run out as well...***

This is the second time it has happened and a consultant send you a reference and four days later , still no response from them

Management is definitely not hands on and doesn't get involved.

I want to be contacted by MTN as I have sent three emails to them already.

What a useless service provider
