Broadband disconnects randomly and when phone is used

[#1]

OK - and you haven't had a response?

[#2]

Yes, I have, it said I need to check the connection inside my home. Haven't had time to do that yet.

I would just remove and reseat your cables (phone/Hub, etc.) and see if that solves it, but years of experience tells me it won't - noise on the phone line is invariably caused by issues on the Openreach network, but it appears from my last fault before I moved to FTTP that they don't like to admit it.
