instructions not followed

i app**** for a contract phone with vodacom a few weeks back. i was very specific with thge consultant in informing him that i wanted to keep my current (pre paid ) cell phone number, as i do not want to change my cell phone number. He assured me that they will activate my existing number to a contract number. I was also told that my devise will be delivered in 5 days- well this ended up taking two weeks. Any how the devise eventually arrived, only to find out that the contract was not done on my existing number, but they have allocated a new cell phone number, and secondly they did not even give the sim card for the new number!!! Vodacom needs to take this contract phone back. i am definately not accepting a new number!!
