Services suspended no notification given or reason

Been holding on to a call to speak to a consultant for +/- 45 minutes. I cannot get through to you at all. I've made my normal payment which I do every month and this month you suspend my services.

I do not get my invoices as I've requested in the past that my email must be updated and yet to date, this has not been updated as well as asked my primary number to be updated as someone added the 2nd contract number as my primary for some reason.

No call was given or reason for why my account has been suspended and you just do this. Now if I had an emergency and it costs someone's life? If I'm not contactable and able to contact I'm not getting paid. This means you will not get paid, I've been a customer for years, and if this is the support/services I get I will stop payment effective immediately.

going to buy a prepaid sim and use it in a backup phone and get rid of mtn, my companies lawyers will be in contact.
