Fiber fault

Good day, I had my fiber installed in July, through Vumatel and the ISP is Flycool. On the 4th of September out of nowhere, there was a green light flashing on LOS. I got in touch with the guy that did the installation and he confirmed that there was a fault and that a technician would need to be assigned, he then logged a ticket for me. Ticket #*** is the ticket number. They tried to get in touch with me, the problem is that I am not using the number I used when I made the order, Khanyisile reached out out to me asking for an alternative number, this was on Sunday the 10th of September, I rep**** on the 11th with my alternative number. I have since been waiting for a call from the technicians to schedule a time they can come and have the fault resolved. May I get assistance with that please.
