Bad customer service and no service for customers during lockdown even over the phone

Mtn is not available to assist customers during the lockdown. They suspended my account and I made payment on the 25th of March, they charged insurance fee to my account which I didn't take. They said they escaped the matter but now my account has been suspended. I call 135 no mtn champion is available but just goes off, I even called head office *** the lady put me through the same number I told her I have been trying to call and no one is picking up. Mtn you are really losing the plot, I'm asking myself why I have been soo loyal to you for soo many years. Vodacom customers have said vodacom is the best and I always stood by mtn, I'm done with you and really considering moving over to Vodacom. They dont even respond to reviews, they say they respond privately to the customer but the customer doesn't receive any response for reviews or complaints raised on hello peter or any other platform
