Vodacom making it impossible to pay them!!!

Last year end May I signed up for a laptop deal via Direct Sales. The lady assured me it comes with Microsoft Office- it never did. I queried it, but was sent from North to South so I gave up the fight. For about 6 months Vodacom NEVER debited my account. I queried it, but was told no contract is linked to my ID. SIX MONTHS LATER they decided to debit from my PREVIOUS account without ANY communication. By then I already switched some debit orders to another bank. For the past 3 months I had a challenge paying as Vodacom keep trying debiting from my wrong account! Insufficient funds! I couldn't even follow up on it as I have never received ANY account number, reference number OR contract number! 3 weeks back somebody phoned me to tell me I will be handed over and my number has been scratched. I informed the lady what happened, but all she said was :So what would you like to do?\. I would GLADLY make the payment had I known whats my Vodacom account number. I phoned *** but they prompt for the cellphone number WHICH I DONT HAVE. Then I tried to sign up online to view my account but the link is not working!!! Yet Vodacom wants to HAND ME OVER? Vodacom isn't easy accessible AT ALL!"
