F$@%ing useless VODACOM NO INTERGRITY

I did a review on Hello Peter that since the 1 April my speed is 106MB where I PAY for a 1000MB line. A agent phoned me and said to me ERIN the manager will phone me, its 5 days later and I had to phone them everyday to try and find out what is the problem. I phoned again now and was promised the "managers" will phone me back... When I said to the lady I will not put down the phone and wait for them to phone me because that "f@%king people don't phone me back she dropped the call. still no help no action no nothing, surprise for them there will be NO payment this month. At lest when you tell your customer to come back to them DO THAT!!
