Poor Service and unauthorized debit order

<p>Whilst going through my bankstatements I noticed that Vodacom has been deducting a higher installment than my agreed contract. When I queried they advised that I took an additional contract for a router. I advised them that the sales agent did contact me and advised that it would be free of charge as I said I am not going to pay for an additional router as I have ADSL at home. I advised them to draw the recorded call and they will be able to confirm what I'm saying is true. They didn't come back to me, however I received a call from the courier for pick up of router, just pitched up at my work without arranging with me first and as a result the router was not with me. We arranged again for another day at my home address and they didn't pitch. Then again pitched at work without arranging. Up until now the router has not been collected nor have I been reimbursed for the additional unauthorized debit orders which have been going off. I called last week, after holding the line forever and being transferred from one department to another, I was told the courier would again contact to arrange pick. This has still not been done. This is really poor service, especially considering that they have been deducting money from my account without my authorization. Can we have this sorted now please? How difficult is it to collect a router and refund me my money? Urgent attendance will be appreciated.</p>
