***** invoicing practices

I have two Vodocom contracts in my business's names which expired early in April. I notified Vodacom in writing that I did not wish to renew these contracts (retrenched the guy who still has the devices in his possession). This was confirmed in writing by Vodacom. Nevertheless, Vodacom still invoiced my company for the whole month of April and helped themselves from my company's bank with the aid of a debit order. I have queried this via e-mail but received no reply. Moral of the story: don't agree to a debit order with anyone. Its impossible to stop.
