Update.
Sofa was delivered and yes I was forced to take a day off work or they would charge me storage. It's not exactly what I thought i was getting but I just cannot be bothered any more. Poor quality back cushions but the rest is fine.
Tried 5 times to get the Saturday delivery money returned. On the 5th attempt threatened them with Trading Standards and at least now I have confirmation that it has been passed to their payments dept. There has been no offer of compensation and except for the first contact there has been no apology for not having the sofa ready when they arranged the first delivery or any of their subsequent failures.
They have to be, without doubt. the worst company I have dealt with in years, probably decades.
I going to try and mentally erase the whole experience. I've even stopped watching Gogglebox as I get angry every ad break.
Thanks for reading my tales of woe.
