Delaying Installation

I have app**** and paid for Vuma wifi on the 5th of May and till today no one has called me to notify me why are they delaying the installation on our premisese. I have sent several emails to *** and also to *** but all my efforts have been to vein.

I received this reference number dated 16 May 2022 SA122494,

Im not happy with their customer service and im not sure if doing business with them will be a wise idea.
