Broken goods, ignored complaint, then computer says no

Toilet and Cistern both broken when delivered. Both packages were poorly packed and looked like they'd been kicked around the depot. They were sent to my office and didn't have a chance to taken them home for a few weeks.
When I got them home they were both broken so I complained.
9 days later I'd heard nothing so complained again.
Another 9 days later still heard nothing so chased again.
Another 6 days later I phoned and was told:-
"You've got to report any problems within 48 hours of delivery - it's in the contract"
I said there had been a 2 week gap from order to delivery and I couldn't be expected to remember there was a time limit. I said it might have been an idea to remind me of this fact when they knew it had been delivered.
Not interested. Computer says no.
They are perhaps cheap for a reason - BUYER BEWARE
I've now paid £150 for nothing and they aren't interested. They haven't said anything about it taking 5 weeks and 4 separate chases to get any response from them - I guess that must be the norm for their customer service.
