Vodacom issue

I wanted to do an upgrade online, which I did, phone and watch delivered, however, when I started setting up my banking details I got stuck as my number was not the same, I went to Vidacom in Key West and surprisingly enough they told me that my line was not upgraded but a new contract was taken out. Which was not correct. I phoned, emailed and did online chat on the Vodacom website, to get the new contract cancelled. After numerous tries that said they can't cancel the contract without having the handset back in the warehouse. RAM collected the phone and watch and as soon as I got the sms confirming that the handset and watch is back in the warehouse I phoned again to get the contract cancelled... I made 3 calls again, still no confirmation that the new contract will be cancelled and no phone either, however they sent my amount due for the month, adding the new contract. I need someone to URGENTLY sort this out and get the new contract cancelled.
