Vodacom Fibre

I have been experiancing difficulty with the modem for the past year and when i called they resolved the issue with in 24hrs i was soo impressed till now. the WIFI part of the modem has not been working since Friday the 17 March 2023 and my daughter is writing her exams online. Logged the call on friday (SR***) called almost everyday to have resolved,spent R500 on data so that my Daughter can learn and write her exams. What angers i have to explain the situation over and over again ,are calls not recorded dont the make notes on the system. i called on Monday there was a lady that asked us to reset the Modem we did and i explained to her we have been doing this all the time and it works for a fe minutes and stops , she promised to call in an hour to check if the unit is still working ,and did not call back. I have to call to get feedback every time . I normally would not make a fuss but i have explained the urgency and no one has given me a solution and not considering my solution to replace the router.
