Impossible to cancel contract

Vodacom Vodacom Customer Care Vodacom Customer Care Hopefully someone from vodacom replies here... My data contract R199/month finished almost 2 years ago. Since then I've been getting regular debits of just over R500/month. No one notified me that my contract was up and I didn't even notice as this was just a backup contract for my business. I've been trying to get hold of a real person at vodacom for ages with no luck. When u call them 1 of the options is cancelations & upgrades which only accommodates upgrades NOT cancellations. I've emailed them too only to get an automated reply template but no real response from them. A once reliable company is in shambles. Can someone please help get these debit orders canceled as my contract was finished over a year ago. Surely it has to be ******* to debit in excess of the R199 I signed for, especially when the contract expired already? I want a refund or a suitable compromise! Cancelling a contact is the most difficult thing with vodacom, how unprofessional it is that u can't cancel at the store where u signed up. Pathetic vodacom, that's ********* too, shame on u guys :-( This is the number I need cancelled PLEASE ... +***
