No broadband until 15th June??

You have a residential service with no SLA, problem fixes are with all residential ISPs ‘best endeavours’. If you want a ‘guaranteed’ SLA you need to purchase a business account service.

You need a backup connection when working from home as you cannot rely on a residential connection:

So yes, 'REALLY'.

BB & PHONE down ALL day again despite getting a text msg at 10.30 this morning advising services now fixed. Complaint raised

I keep saying this. Get a backup of a MiFi router and a data-only SIM card, plenty of options with periods from one month. This is your responsibility if you WFH.

get one of these with a SIM for backup add a switch for more ports

Zyxel 5G NR 4.67 Gbps Indoor Router | AX3600 WiFi 6 Router | App or Nebula Cloud Management | Share WiFi to 64 devices | Dual WAN failover [Nebula FWA510] : Amazon.co.uk: Computers & Accessories

The mobile being used for these posts clearly has data & coverage , it can be connected 
as a Wi-Fi hot spot or ( I prefer ) via USB cable to get an office laptop back on line. 

Folks on a WFH basis need to have Plans B & C ready to go for internet or power failures.

Be sure to get the compensation you are due from VM.
