Unauthorized debit order

<p>I had a two year contract with Vodacom with anniversary being o 30 June 2016. I had called in prior to this date to cancel the contract and again after to confirm it was done. Vodacom continued billing me for July and August. On attempting to correct this, I have called and emailed numerous times (with reference no's to show). Vodacom does not dispute that I am owed a refund but without fail, Vodacom fails to refund the amounts for over 4 months now.</p>
