HORRIBLE SERVICE FROM VUMATEL

We ordered Fiber and a technician came out to site to install. Arriving he tells us that he cannot install it as we have to provide the route. Provide the route? Yes trench - so we arrange for the trenching and he advises he will be back next day - Saturday morning at 8:30am. Not even an hour later the Vumatel coordinator phones to confirm that we are aware that we have to supply the route - then she starts - sorry the technician does not have the authority to make appointments he can only come back next Tuesday at 11:30. I tell her it is not acceptable and she gets him to phone me. Very apologetic I am forced to take the slot at 11:30 next week Tuesday. Tuesday comes and he spends an hour "installing" only to find that he tells my lady on site "sorry no fiber". It is now 2 weeks later and NO one can tell me what is actually going on - NO one returns my calls or emails and the best of all is that both the technician and the coordinator now swears high and dry that they never told us to trench. Even though I have them both on call recording requesting that Vumatel is refusing to take responsibility. If there is no fiber suddenly like you told the lady on site - Why has NO ONE contacted me? Why would you ask us to trench if it is not needed? If this is an honest mistake made by the technician - Why not just own up to it? Why are you now denying the request making it out as if I am lying? VUMATEL HAS LEFT ME WITH AN OPEN TRENCH NO FIBER AND NO ANSWERS FOR 2 WEEKS
