Continued poor service from Vodacom

We need to change from pre-paid to contract. We requested the number to remain the same from pre-paid to contract. A new number was however allocated. The problem was bought under the attention of Vodacom on 17 May. Since then no solution could be offered - feedback remained at "they are still busy”. The problem was reported on Hello Peter on 13 June were after Vodacom did phone back - They would have investigated the problem....no further feedback received, or solution offered
