WORST CUSTOMER SERVICES

I took a contract with MTN in January or February 2026, end of March I contacted MTN and requested to listen to the conversation had with their Sales agent, which I was informed that a supervisor in the sales department will call me, which I have followed up more than 5 times until to date I have not been contacted and have made numerous calls to MTN and have been sent from pillar to post until to date I'm still waiting for the supervisor to call me.
