Unauthorized debit and ********** activity

Unauthorized debit off my account after canceling and was assured that I would receive a refund. After being misled and directly after that ********** activity was detected on my account. This customer service is totally unacceptable. Vodacom is a bunch of *******. *****ing money from a retired woman. You should be ashamed. I trust the refund of all of the debits will be refunded to me by the end of the week as I will be canceling my contract on Saturday if not. I would also like an investigation into the ********** activity which seems to have stemmed from the Vodacom rewards.
