No network coverage and no active help

I'm living in Utrecht Kwazulu natal and since you are using vodacom I have no network coverage. I've been to Telkom mobile in Newcastle twice and contacted your customer help service but nothing has changed. They did a sim swop. My husband has already switched to another service provider but because of the fact that I have a contract with Telkom it is not that easy to switch....I am paying for data that I cant use and am desperate. I am considering to launch a complaint on a platform like hello Peter!
