Solid red light Hub 3

I have a solid red light on my Hub 3 which has been there for about 2 months.

I have restarted the hub, blown the device it with a mains powered electronics cleaner, restarted using the pin hole and still the light remains. All of these steps have been repeated numerous times.

When my hub starts up after being reset (which it does by itself), it takes almost 30 mins to start both ethernet and WiFi. I'm worried that it'll give up and won't initiate any connection.

I've had the hub since 2017, and been with Virgin since at least 2013, and upon calling the customer line and speed tests being run, they have told me that I'm not able to get it replaced, not able to buy a new one and not able to swap for a refurbished one. Unless I upgrade my package to a higher speed, or experience more serious connection issues, I've been told it's not possible to get it replaced. I'm out of contract and willing to start a new one if I'll get a new hub but I was told upgrading to 1gb is my only option.

I don't want a new hub for fun, I just want to make sure my connection isn't interrupted as I work from home and need it all the time.

Any suggestions for resolving the problem?
