Worst Service ever!

I eventually got my right sim from the couriers, so i went into the Vodacom shop to get the activation sorted out, the guy said that they already activated the previous sim and therefor we need to do a simswop, so we did and he guaranteed me that in the next 4hours all will be done, its more than a day now and still nothing. This service is absolutely unacceptable for the Best selling Service provider in the country?? I have 2 other contracts with Vodacom and i will stop all 3 of them if this bad service continues
