Vodacom ****mers

What a ****!! Got phoned from this number +*** to talk about my contract pricing. After telling the lady a 100 times that I am not interested in anything if it means my contract will be extended as my term is coming to an end in a couple of months. After ensuring me everytime that I do not have to worry it will not be extended low and behold 5 minutes after the call I receive an sms that my contract on number ***and *** has been extended by two years!!! Now I have to struggle to sort this out?? What type of customer service is this to trick someone into a contract after I expressed my wishes on numerous occasions that I do not wish to do so. Looking forward to someone contacting me to sort this out - Carli Steyn
