No consistent internet connection (Fibre)

I have been a loyal MWEB customer since the 90's. In December 2016, I changed from ADSL to Fibre, and guess what.... Here my problems started. We consistently have to reset our MWEB router on average about once every two days in order to re-establish internet connection. Sometimes it's two to three times a day. I assumed this could be due to teething problems with the Firbre supplier, etc, because it is noticeable how often we have seen them in our area with a man-hole cover open. Anyway, I have been logging queries on the MWEB web page over the last 12+ months, and they just keep getting closed - but my problem persists. I assume that MWEB's technical staff get measured on how many open queries there are and how long they take to get closed. So, just close the query. I assume the technical staff's KPI's, bonuses and/or incentives are linked to queries being resolved. Well, my query is still not being resolved, even after 12+ months
