INABILITY OF VODACOM'S ACCOUNTS DIVISION TO CORRECTLY IDENTIFY CUSTOMERS

I have had the same Vodacom cell number, almost since the company started - that is to say for almost 20+ years. HOWEVER, for the last couple of months, my number has been linked - BY VODACOM - to various other customers. The latest in a list of bad experiences is the fact that Vodacom's Accounts division has handed over their list of arrears customers, linking MY TELEPHONE NUMBER with a certain BETTY MAFARO. I have had COUNTLESS calls, sms's, all of a threatening nature, from various debt collection agencies, the latest a company called VVM. According to VODACOM it is MY RESPONSIBILITY to have my number removed from VVM's database. BUT I AM NOT THE ONE WHO GAVE MY TELEPHONE NUMBER TO VVM AS A CUSTOMER WITH AN ACCOUNT IN ARREARS! I have also paid my account via EFT as per the past 2-3 years, and all of a sudden, my payments do not reflect on MY Vodacom account. HOW DO THEY PROPOSE TO DO BUSINESS if they cannot allocate your payment to your own account?????
