Cancelation issue

Worst cancelation experience. Can anyone help me to cancel my two lines *** and ***?

I have already called in April and notified the cancelation department, which they did nothing and I have been billed again with no cancelation done.

Is there anyone willing to help a customer as this is outrageous.

I want to be refunded for all the months after April as I did my job and someone at Vodacom clearly does not do theirs.
