Bad experience

Receiving calls daily to upgrade, when you do they tell you it lasted for 2 months you have to upgrade again. I have been harassed the last 4 months on a weekly basis just for them to tell me I have to upgrade again as their 3rd party company gave me incorrect information now I need to pay more. I am completely devastated by the service I have received over the last 4 months from Vodacom. I have been a vodacom client for many years but this has pushed me to a new level. I had to put the phone down today as the Vodacom supervisor carried on so badly I could not deal with her.
