Home connect support service is horrible

Home connect is a good service provider but when it comes to support they are horrible, I mean is anyone even working on the support side ? My internet has been down for a while now and I’ve been trying to contact them regarding this the whole time and the result is, no one is answering the phone and on what’s app no one is answer?

I’ve been having this issue for a while and the agent tell me to separate the 2.4 ghz and 5 ghz band but I don’t understand what does that have to do with my internet being down if it’s not even the routers fault but I did it anyway? I find this out by connecting another router that I know it works and the same issue is happening. This is getting very frustrating, out of no time my internet will be off for 30min-3 hours and I need it to work from home.

I’m also working in the IT Industry and I also know what steps to take to identify the error. And I also understand it takes time to investigate but it doesn’t take a few months and the answer I got was separate the bandwidth and it’s case by traffic ? Traffic for a 30min to 3 hours? I don’t think so ?
