Drop calls and network

Over 2 years I've been complaining about drop calls and network with MTN and it seems like it's getting worse every day. Nowadays I can't even call their call center. Last year they offered me R6300 as their re*****ion compancesion of which I agreed. But now I regret doing why I took it, I even asked my wife not to upgrade cause we complain about ******** change on her account of which they agreed that it was done ********ly. MTN is not a network you can trust.
