Intermittent internet not resolved since October 2023

I have been having an interment service since last year October which I reported a number of times . The WiFi router will just switch off an on . It sometimes does this for 2/3 times in a period of 39 minutes . I have reported the issue in October and Metrofibre just closed the ticket without providing feedback. I logged another one and still no feedback. I work from home and this is very frustrating especially while I am in the middle of online meetings. The support service is pathetic. 1st ticket number logged in October # 349340 and closed without any feedback. 2nd ticket #138126 and still no feedback . Metrofibre should just advise if they are failing to resolve this so I can take my business elsewhere. I am just giving them till the end of the month of no feedback I will not be continuing with them
