VUMATEL AND MWEB COMMUNICATION POOR

I am a customer already with Mweb for the last 18 years. Service between Mweb and Vumatel is very poor. Mweb send messages to activate Vumatel but then emails come 3 days after installation that installation will be done on the 20th April 2022. I need line activated because installation was already done. When i placed the upgrade i mentioned to them it is not at my primary home but another premises and now it seems that Vumatel did not capture that. Even if they arrived at the correct address to do installation.
