acconts

I cancelled my account with Vodacom 2 months back served my notice as my contract was over but surprisingly today i got an sms that my account has been handed over <br> today i spoke to Nqobile in the accounts department who told me that the was an invoice issued and it was not suppose to be as the number is on prepaid . She then transferred me to Retention where i spoke to Lesego who told me also she cant see anything then she took me back to accounts and the number just rings<br> You have to sort this out and 1 of the reason i don't want nothing to do with Vodacom .
