Supersonic WIFI serious breach in service delivery

I have had repeatedly phone Supersonic to assist my elderly parents. The issue with Supersonic is that every too often their WIFI is disconnected. We phone in and after lentghy process and struggle their WIFI is restored. Supersoninc keeps changing their address from CNR of CHARL AVENUE and ****OIL, Kameeldrift wes Pretoria to Charl Street Pretoria. My parents do not reside in Char street. its quite a distance away. We keep correcting it - with the help of an agent and for some reason the system just keeps going back. My parents have a month to month LTE and their WIFI has been off now for nealy two weeks. Tomorrow is the end of the month and the remaining GIGs are then also lost. They have to additionally also keep praying the full amount regardless of the technical issue being on the company's side. Supersonic WIFI does have a whatsapp chat, but this function has been under "maintenance" for a while. In the past we via the whatsapp sent a Pin drop of their location to have this issue fixed. I phones the 26 February 2025. Their WIFI was restored for only 1 hour and off again.

This is really getting to poor sercive delivery. Why does Supersonic's system keep doing this? There are many customers in the area, but why my parents' account? Will this breach of contract be fixed? Will their lost GIGS be restored to them?
