Disappointing support

I've been a loyal customer of Home-Connect for quite some time now, but the recent experience with their support team has left me extremely disappointed.

For weeks, I've been facing connectivity issues with my internet connectivity. Despite numerous attempts to resolve the issue by contacting their support, the problem only seems to worsen.

After several troubleshooting sessions, Home-Connect decided to replace my router with a refurbished one. However, this change has only made things worse. On a 100/100 line, I get 90/90 on a good day but it ranges from 90/90 all the way down to 30/1 with most days 50/20 - this while standing right in front of the router and being connected on the 5G band.

To make matters worse, Microsoft Teams calls drop on a daily basis disrupting my work. Streaming on TV is almost impossible at night. The TV is connected to the router via Ethernet cable.

I have again logged another support call, but as usual no feedback or response.
