No technical expertise to solve problems!

With reference to queries: MWB***0 MWB***0 MWB***4 I have for the past 2 weeks been struggling with severe packet loss on my 300mb fibre, even gone as far as buying a new router and replacing the **** zyxel with my own router. All my queries get closed after 3-4 days with "We have reset your port and tested the line but dont see a problem" I have included screenshots of traceroute's and mtr's which clearly show I have packet loss from the second hop out from my router yet the queries get closed without resolution to my problem. I will probably be moving to new ISP and I dont recommend you use mwebs service if you work from home as I do.
