Vodacom Difficult to cancel contract

I contacted Vodacom to cancel my contract which has now lapsed. The email address given to cancel the account is as follows [Email Removed] . As you can see from their email address they are trying to use the most complicated email address in order for clients to get the wording wrong. As a result the cancellation letters will not come through and you will pay for another month of service. Vodacom please be reasonable and use a simple email for the millions of clients you service. Ridiculous
