Pathetic Service of Vumatel

I would like to voice my extreme displeasure at the levels of service and general interaction I have with Vumatel. During the course of last year, Vumatel laid infrastructure in my complex for purposes of utilising fibre. Each unit at my complex was then fitted with a "box" so that fibre could be installed. My complex is situated at Northcliff Johannesburg. As i already had a LTE contract with another Service Provider until the middle of August 2018, i decided to wait for that contract to expire before choosing an ISP via Vumatel. During the end of August of this year, i made an application for a service with an ISP via the Vumatel website. The ISP informed me that i would need to contact Vumatel in order to arrange an installation before i could utilise their service. I then subsequently made contact with Vumatel (in August) and they informed me that their network was undergoing an upgrade. Which meant that they could not do any installation for me as the upgrade would take 6 to 8 weeks. Vumatel informed me that once the upgrade was complete they would contact me to arrange a date for installation. Finally i was contacted by Vumatel in November to arrange an installation date. Vumatel technicians attend my premises on the weekend of the 17th to test the box at my unit. The technicians informed me that they provisioned, the line, that it was active and that an installation would be arranged. Subsequent to the 17th, i received an email from Vumatel on the 26th of November to choose my ISP. I subsequently did this and was given the following reference number: VT-19 ********** 79. I then contacted my ISP today to find out when can installation be done to activate my service. The ISP informed me that they need to liaise with Vumatel to arrange the installation date. Thereafter i received a call from the ISP who informed them that my installation could not be done, as there needs to be an "AG Port upgrade" at my unit. This was never made known to me at any stage during my numerous calls with Vumatel, nor did the technicians mention a thing. The ISP also informed me that they don't have any idea as to when this "AG" upgrade will be done, as Vumatel did not provide them with any details on turnaround times. I am thus beyond frustrated as i am going nowhere slowly with Vumatel. Their customer service is pathetic. My interactions with them, has provided me with no assurance as to when my service will be installed. I was on the phone for about half an hour today with an Vumatel call agent, who informed me that a woman called "Stellen" (not sure of name) would contact me. As is obvious, i have not been contacted
