MTN Customer Care service is as bad or worse that the SOEs

MTN has fallen far from where it was 20 odd years ago. I have tried unsuccessfully to cancel 2 data contracts that we no longer use. After hours of my time waiting in a phone queue, I eventually got through to an agent on three separate occasions, and nobody could assist as the data linked to my ID number is apparently loaded on the old Eppix system (As I have been an MTN customer for over two decades - nice loyalty reward!) On being transferred to someone who apparently could assist, the line is either not answered, ends in you being placed in another phone queue for hours on end... or just goes dead... or gets cut off by the agent... Trying to speak to an agent to change limits to enable international calling / SMS roaming on some of the numbers under my account is similarly problematic (The MyMTN App) has an un-moveable limit set to zero!!! The last approach attempted was an email to Customer Care... I got an immediate automated response to say my email had been received, but getting further with intelligent life the other end of an email appears to be more of a challenge
