Billing nightmare

First two months of a contract double date that is R549 a month, I was being charged R2500pm for. Eventually sorted.....recieved 20gig daytime & 20 gig nighttime instead of 40 +40 gig. Data goes sooo quickly asked for URL report only to be told they cant help me. Do the *180* thing says no email linked to number. Enquire how to link email to my number, 3 weeks later still waiting after numerous emails. I have been a man client for 15 years & their lack of customer service & outright theft is unforgivable. Never will n sign another contract with MTN. Nightmare since day one of their double (half) data (4xcontract price thievery)
