Legal status

For a whole business like I’ve been getting really terrible service from MTN now this is above and beyond and probably my last stroke never taking even a prepaid sim because you don’t value my business to think I’m about to lose out on my dream house because of the incompetence and attitude revived from MTN it’s disgusting. How was my account referred to an entire legal and flagged with me being told? How is that I use the services and the invoices are 100% correct but somewhat I’m handed over to legal dear MTN I need answers as I’ve had it up to here with your nonsense it abuse honestly yerr
