Vodacom is robbing me

On the 23rd of January 2015 I received a phone call from Vodacom thanking me for being such a good customer. I was offered a Samsung 10.1 tablet on a special offer. I accepted the offer. Shortly afterward I received the following SMS : A vetting application for a new line has been registered against your Account : ... Please phone contact Dealer REWIND on *** for any queries. Vodacom.<br> <br> The tablet was to be delivered to my work address within 3 days. I still have not received it. I phoned this number yesterday and to my surprise it does not exist. I then phoned Vodacom on 082111 and was put through to the Sales Department. The gentleman checked my account and found no new product added and no trace of any Tablet added to my account. He informed me that it was not Vodacom!!!<br> <br> The SMS as stated above was received in the same \conversation box"\"" as my previous upgrades from the same number *** all done directly with Vodacom. I have kept them all as future reference.<br> <br> my account has been debited with the new amount but i have not recieved anything.. please let me know how can you debit me if nothing was sent???"""
