Vodacom

I am sick and tired of people phoning me about Vodacom account, for the contract I cancelled long time ago. I think it's more than 2yrs now the more I tell these people that I've cancelled the contract the more they phone. They even had the guts to ask for the reference number, where will I get the reference number after such a long time. Vodacom is the worst service provider that I ever had, I had a bad experience with these people they gave me open plan instead of fixed amount and Charging me huge amounts and everytime I asked for explanation, they could not explain I decided to wait for my contract to end and cancel everything thing with them, but now they still harrassing me NO. Please sort this out it is not my fault that your employees did not stop the contract you can see for yourself that I have never used your SIM card after that. STOP PHONING Me
