Vodacom mall of Africa pathetic service

My mum had taken out a contract for me so I was asked if I want to keep my prepaid number or get a new one so I did opt to keep my prepaid number , but no consultant made me aware that I would be losing all of my talking points if I opted to change my number , I have spoken to vodacom customer care they have advised me to go back to the store that I had took out the contract with , I even did that and yet they were of no help at all , they do not want to allocate my talking points back to me and I had over 1000 talking points , if only an agent explained that I would be losing my talking points I would have never opted to swop my prepaid number. I would really like feedback on this if I need to be contacted my prepaid number is ********** 931 And this happened at the vodacom store at mall of Africa I have tried to even call them numerous times but no one answers the call
