Vumatel Lack of Service

I changed ownership of our internet via Mweb to my name. Mweb has been amazing, but the fibre box is Vumatel. This change over was done on the 01 April, 07 April Vumatel was back because their line was not been picked up! Vumatel technician confirmed that someone at Vumatel activated on the wrong line! The 08th of April, still no luck. The Vuma ticket confirmed mix up with lines and case was closed!!!!! I have been sitting via live chat with MWEB from 01 April, and after 8 days Vumatel still has not resolved, nobody gets back to you and I myself and to follow up!!!! What the hell??? Is this how Vumatel conduct themselves! It has cost me airtime and data as I work from home, with no resolution in site!!!!!!!!!
