Billed for number not in use.

I had 3 numbers with Autopage. I didn't renew my contract due to double billing that was debited from my account and never paid back.<br> The other number, was my husband's number that passed away 3year's ago and the contract was cancelled immediately.<br> Now, after 3 years I am receiving invoices for that number again. Last month R580.50 was debited and today the same amount. Why after all these years are amounts being debited for a number no longer in use? The invoice is in my late husband's name but is debited from my account? Please explain!<br> I only have one number on contract with Autopage and that is for 3G mobile data. And with this service, I will have to cancel it as well as soon as contract ends.<br> It is always a problem to get anything sorted out with them.<br> Will I see the money refunded this time?
