Vodacom **********!

I recently received a call from vodacom last week where they presented me with a scheme in which I could receive 15gb data for R299 or something like that. At the time I was busy I told them to call the next day. The next day the lady calls and presented the scheme again I then declined it and cut the call. During the weekend I then went to a vodacom store to get a contract for a laptop. I was then told that the scheme I was presented with was pending! Even though I declined it. I then called the customer care line and no one was helpful at all I requested the call records! And nothing!!!! Vodacom this is not the first time!!!!! Vodacom is the worst service provider! They are not professional and extremely rude!!
