Extremely shocking service delivery

I've had no internet connectivity since 07/02026. Logged a service request with Vodacom (my service provider) on 08/01/3025 who logged a service request with Vuma. The first response I got was a email from A gentleman on 12/01/2026 saying they could not get hold of me and mentioned in the email 2 old cell phone numbers that was last in use in 2017. I responded to the email and gave vuma my new numbers. A lady from Vuma contacted me and said that a technician had been assigned and was due to look into the fault on the 13/01/2026. I explained to her that I am work and should they need to get into the house to check they must please call - nobody pitched. I've contacted Vodacom again 14/01/2026, they contacted Vuma, to which Vuma's response but we have been trying to get hold of the client. I have both of my cell phones with me 24/7 and have not received any phonecalls.
