Disgusting service from mweb/vumatel

I was using mweb for 2 years.I moved premises in December and called Mweb to move my fibre to the new premises.However I was told that I will be linked to vumatel.I was told that I need to sign a new 12 month contract.For the past 2 months technicians have been sent up and down.Vumatel blaming mweb and so forth.I still have no internet with thousand stories from each provider using one another as a problem. I am billed for a service I don't have.I am struggling to cancel the contract and refund my money which was paid for services I never received. as I am continuously been put on hold or transferred to a different department.My cell phone bill has increased miraculously calling this service provider with still no resolution to the problem.With no service I received a message stating that my package will be increased from R499 to R685.I just want to cancel and I want my refund from either mweb or vumatel.
