Don't sign a deal with the devil

I would never recommend Vodacom to anyone, everywhere I go I will make it my life mission to inform people how ******** and *********** Vodacom is, I'd rather sign a contract to sell my soul before ever signing anything related to Vodacom again. It's been over a year since I've had anything to do with Vodacom and they are still opening enquiries on my name and adding enquiries on my credit report, and whenever I call them to find out why they doing this or what is going on I'm being told they cant help me because my account is up to date and I dont have any vodacom contracts so they cant help me, I've opened so many enquires and till this day nothing gets done, all I can do is sit here and watch my credit score decrease every other month because vodacom refuses to help me because I dont have a contact with them and they just wont leave me alone!!!!!
