network

I have a blackberry which obviously uses data.R60 data for a 30day period,however on saturday the 6th I started experiencing terrible network coverage where I could not make or receive calls or use any of my data services.I fone customer care on the 7th and was told on their side there was nothing wrong with the network but the would log a complaint.on the 8th an agent called to confirm that there was a problem but it was resolved(in actuall fact it was not)she said she would call me the next day to see if I was still experiencing the same thing(she neva called back)today is now the 11th and still this has not been resolved.iiv paid to use data services but for 1 week I was unable to access this.I am unemployed and sent my cv all over,an employer could be trying to get hold of me but would be able to bcoz of the poor network.vodacome needs to reimburse me for the days iv lost out on data services.I am seriously concidering changing network providers.
