Poor network issues

When I first got into business with them they were super helpful. I guess all they care about is numbers and then care less about keeping the good name. I have since been struggling with connection 2 months ago, been requesting a call back atleast 16times a day, I lost thousands of rands trying to call them with no luck. Instead, I am being told to hold the line. I have been receiving useless, coding emails from them which I can't even read or translate. Yet they had a nerve to inform me about a payment increase.. I am slowly loosing interest in you and it's barely a year being with you.
