Harveys sofa won't fit - customer service shocking!

I ordered a 3 seater sofa and recliner chair from Harveys 12 weeks ago. At the time I was still living with my parents, because although I'd completed on my house I was decorating before I moved, so when it came to paying the deposit it had to go down as my parents' address as that's where my credit card bills were going to. Salesman took details of new address and said he'd change it on system once the deposit went through. That obviously never happened because when they rang 2 weeks ago to book delivery they thought they were delivering it to my parents house! Spoke to store and they again said theyd change address, again got a phone call to arrange delivery with wrong address! Took until last friday to sort this, agreed delivery for today.

At no point was I given any dimensions of sofa, or asked to measure doorways etc. All I was asked in store, then again over the phone when booking delivery, was were there any steps up to the house (1), any corners to get the sofa around (none, it's straight through the front door, through the porch, into the living room) and was it going upstairs (no).

Delivery arrived today and before men even got the sofa off the van they were tutting about it not fitting. Bearing in mind there's 30" clearance at the front door, and 29.5" at the porch door, I don't exactly have narrow doorways! They had the cheek to tell me most people have sofas delivered through patio doors, which I find hard to believe because there are lots of houses without patio doors, and even those that have you still need to get the sofa through the internal doors into the living room!

Anyway, turns out they were right, they couldn't get it in, basically because depth of the back of the sofa is too big (33"!) although they didn't try very hard, because, in their words, if they damaged the sofa trying to get it in the damaged sofa would then be mine!

Delivery men were less than helpful, all they could say was I needed to speak to the store, so I phoned the store and agreed they could take it there. So my sofa and recliner chair are currently sitting in the storage part of the store. Man in store then told me that they know an upholsterer who would remove the arms of the sofa to get it in, then replace them once its in the living room, but apparently I would have to pay for that.

After all this I got my paperwork back out. Nowhere on my invoice does it give me the dimensions of the sofa. Call me naive but I would have expected them to inform me if there was likely to be a problem because of the size of the sofa, considering they didn't give me the info about the size so I could check for myself.

I'm a touch cynical about this whole thing anyway, because the man from the store was very quick to suggest this upholsterer, sounds almost like a scam! I wonder if they're on commission for referrals to him? Upholsterer doesn't actually work for Harveys, he's self-employed, so it wouldn't surprise me!

Let's see what tomorrow brings, but any advice would be gratefully appreciated in the meantime, particularly anyone who has contact details for Harveys head office. Man in store gave me address but either couldn't or wouldn't give me phone number.
