<p>I took out a contract for a data bundle of 2 gb which included a samsang tablet. This has never ever in all my years been a subscriber to Vodacom has happened. The number that they gave me with the data bundle has not been changed by the previous owner and I constantly get messages and calls to do with the previous owner who the reason why he never let people know that he no longer has the number that I was given was because he owes money everywhere I have found the previous owner of the number on Facebook and he still is using the number that Vodacom has given me. When I asked Vodacom to please change the number cause I'm tired of receiving messages and calls to do with the previous owner they said I must pay in order to change my number. Why must I pay to have my number changed ? Please advice </p>
