No resolution to our Fibre Query

We had Openserve Fibre installed 2 months ago. Everything was working perfectly and then stopped working at the end of March. We phoned Vodacom and were told that our fibre had been cancelled but they could not explain why. It is now nearly two weeks and the matter has not been resolved. Every time you phone the call centre everthing seems to be out of their control. They cannot even get our address correct We are sincerely considering moving our 5 contracts to another service provider becasue service is not what we are getting!
