Billed for phoned returned

Hi,<br> As if having my one problems with Vodacom for the past year, insisting I pay for a non-existent contract, is not enough..... My father returned his phone (with RAM) within 7 days from receiving it but they do not check bank statements and did not realise that Vodacom still kept charging them for the phone for over a year. My mother went to the bank and stopped the debit order and then the threatening phone calls started. They get phoned once a week and are told that they have been reported to the credit bureau and they will come and take the furniture for the amounts outstanding. And this after they were told my father has RAM return paper and the name of the person at Vodacom who received the phone back!!!<br> They think because my parents are elderly they scare them into paying, it is truly unbelievable how bad Vodacom services is.
