a week later Wi-Fi still not working

My Wi-Fi stopped working on the 4th of September. Since then, we have been making calls and sending emails to have this resolved. Technicians came on the 5th but failed to reconnect the services. For some strange reason, the services were finally restored on the night of the 9th, but they only worked that evening and went off again the following day. We depend on the internet for work and TV, and since then we have been forced to buy data. This is extremely frustrating, and I am definitely going to lodge a formal complaint with ICASA, as we are paying for services we are not receiving. Honestly, I cannot encourage anyone to use Vodacom, every month there is a problem with this fibre. Can this matter be escalated to management, because clearly the people we lodge complaints with are not fit and proper to handle them or ensure they are attended to adequately.
