Vodacom online store

Online store called me last year November, I took a contract of uncapped sim and rooter. It was approved. The ram courier wanted at work late while I am home. I was asked to change delivery adress, I used home adress ram came early while I was at work. I asked them to drop my parcel at Lakeside vodacom I will personally collect there. They refused. Upto now I don't have internet at home. When I go to the shop they say I must sort it out with online people my account is blocked. I have been with vodacom for the past 15years.i want my cell number to be prepaid now. Thanks for nothing
