Pathetic Customer service and communication

my services was paid upfront for my Vuma fiber installation technicians did come out for installation however did not complete the installation and did advise that someone else will come out its been 3 days and still no one contacted me and no feedback as to when my services will be completed web Africa advised my order is on hold and i must wait for feedback from vumatel . Time for web Africa & Vumatel to debit was fast but to assist they cannot do their required job description by assisting us as account holders. now i cannot work from home because of their inconsistency.
