VODACOM : DO NOT UPGRAdE ONLINE!!!

I find it difficult to describe how frustrating I have found the Vodacom upgrade service. I opted to upgrade online via my browser afterwhich i received a call to certify my upgrade. I then after a while realized I was being double billed and have a new number. I most certainly did not opt for a new line. I went to a vodashop where they tried to assist me but were unable because another outsourced company sold me the line who were unwilling to cancel the second line? The company apparently called "LikeMindz". I have tried to call them but the number I have goes directly to voicemail. This is incredibly frustrating as no one seems to be able to help me. How ridiculous. I have tried to have LikeMindz provide proof that I agreed to a new line but cant seem to get them to reply to my emails or pickup the phone. After years of using vodacom i am bitterly disgusted. DO NOT UPGRAdE ONLINE. I am still trying to get this sorted out as I cannot lose my number because it is my business line.
