Very poor service from Vodacom

I was sold a WiFi contract with 50/50 speed just to find out I don’t have coverage in my area. Getting Vodacom to cancel the contract has been a headache of note. They dont phone me to arrange collection of the router and close all my incident numbers without resolution. I feel like cancelling all my contacts with Vodacom due to the bad service I received. I can guarantee that they will close the new incident number also without resolution. My frustration has reached the roof and I am out of patience with them.
