Apaulling service

I blocked my number about a month ago due to phone being ******. A month later I get a new sim card and ready to do a sim swap. On monday 11 May 2015, I called the call centre to do the sim swap. Only to be told that my number is under contract. A contract that i was offered but yet never got the details of nor have i ever used the airtime, cause when i was offered it i asked for the details of the contract to be sent to me which never did. Reason I wanted the contract was also to excercise my right of cancelling within cooling off period should i find that i am not happy with the terms of the contract. I have to now deal with the people that got my number *******ly under contract in order to do the sim swap. In contacting them I had to make more than one phone call and an hour to finally get someone that was able to move the request priority and get me the necessary auth letter. However I still was required to go to vodacom outlet in order to have the sim swap done. Mind you i was told i'll only need to present auth letter in order for vodacom to go ahead with my request. To my surprise at the outlet they also needed a copy my ID and the person that issued the letter.
