Double delivery

I ordered the unlimited wireless broadband and it was finally delivered (router and antenna). After about a week or so I received another delivery of the same thing from Telkom. I then realised that I am being billed for both devices even though I only ordered one. <br> <br> I called all the contact numbers available trying to explain this situation to no avail. I finally got through to someone who advised that I should take the extra device to any nearby store/branch. I went to Brooklyn Mall Telkom store only to be told that, that is a franchise and they are not in a position to take the device back. I made my way to the Menlyn store only to be told that they cannot accept the device because I got it via the website. They gave me the Sell Direct number to call but no one answers the phone. <br> <br> The debit order that goes of my bank account is for both the devices but I am only using one of them. The other device is still sealed in it's original courier box.<br> <br> Can you please send someone to come fetch this extra device and please stop debiting my account for something that I did not order or ask for.
