HORRIBLE SERVICE FROM VUMA

Terrible experience from their call centre, 3 days of being their customer but I feel they don't respect their client's complaints seriously. Had an installation done on 27 Nov, have never had connection till today being 29 Nov. Called the call centre since 27th,got promised to be called. Only was called by a technician afternoon of the 29th where the technician asked me if i know of any other Vuma customers struggling with connection and promised to call me bac. About an hour later I get an email saying a technician will visit me with no exact time frame of the visit. Payment was made but I haven't enjoyed any connectivity. Worst decision ever
