Bad service

Vodacom has been debiting my account for over a year. I cancelled my account 2 years ago. Every time I try to block it a different one pops. I have been in contact with them regarding this matter. I received no help and no one can trace or assist. I find it very unprofessional for such a reputable company to give such lame service. I actually blame myself for trusting their services in the first place. I will never use any of their services ever. To everyone who has a contract with. Vodacom check when it expires and cancel it, if you don't they just continue to debit even if you didn't renew it.
