********** Billing to my account

Vodacom **********ly issued a cellphone to someone else using my 3G card number. I've had may call to Vodacom - not 1 from them, and have a letter from Vodacom dated 26 February 2015 from Siphiwe Makhuo in Forensic Services confirming the *****.<br> I received an SMS on 2015-03-11 @ 18h59 advising a credit note of R8421.05(Excluding VAT) was being passed BUT my account stil shows I owe R9600 and that the ********** handset upgrade is still in effect.<br> HOW DIFFICULT IS IT TO PASS A CREDIT NOTE?????? <br> Clearly their service has not improved since my last report on 18/9/2014. I now cannot buy property etc as I've been told I have a bad credit record from Vodacom.<br> PLEASE FIX THIS STUFF UP SOONEST OR FURTHER STEPS WILL BE TAKEN.
