Attrocious service , and theft from Vodacom!

writing another review for Vodacom because once again , I am still getting statements and invoices. The statement has an incorrect address which I do not recognise. This was changed exactly when I received a phone call saying I had taken a new phone!!!I am paying for a phone I did not purchase. I was called by vodacom and assured this was ***** and would be addressed. I have proof that my address was changed on the statements, and all those funds are from a ********** phone. I have been on phone calls repeatedly and assured this would be fixed. Its December and I have paid R1600 over the last 4 months incorrectly!!!Please can I get some help!!!!Surely I should also be refunded!!!
