Unacceptable service

I'm mortified by the poor low service vodacom provides. I took out a contract with vodacom a month ago which is fairly new. My simcard is blocked and requires a puk number. I current in a different city left my particulars at home. I tried to get to call center write emails to recover my number instead I'm snet to bolt who requires the number that I don't have and requesting. I tried to get through to the call center agent with fail. Instead the call center even blocked my number because of the number of attempts I have tried contacting them. I have a meeting in a hour and can't access data as I'm blocked. I checked on all the invoices my number is not mentioned anywhere plus I've been with other service providers this is a very simple query and I'm very fearful if vodacom fails to resolve this in future how are they going to service me.
