Need Guidance on how to proceed with a Virgin Media issue

I had a very similar issue earlier this year with Vodafone. I have ended up with my base station under the sink in the utility room in order to be plugged into the router, which in turn needs to be plugged into the ‘master socket’. 

After my complaining Vodafone did attempt to move the master socket to somewhere more accessible but this failed and we/they reverted to the under the sink placement.
I was fuming that Vodafone hadn’t warned me about this ridiculous set up and I had been so careful to explain that my landline is very important to us before we agreed to Vodafone taking it over. But I’ve now calmed down and moved on. However living in an area with dubious network coverage and  flaky Wi-Fi I have swapped my own SIM card so that my husband and I have mobile phones on different networks. When the Wi-Fi is down, the landline can’t work and neither will hubby’s phone  but I’m still able to communicate!
