I don't know the legalities of it, but since they gave you a replacement product without your consent, I doubt they have the right to set a deadline of acceptance or return.
By saying the OP has to deal with what they got because they didnt respond
If they can prove they were on holiday I am sure the shop will be required to give the money back.
Also OP - if they sent you items you didnt wnat then they hsould pay for the return - they have no right to assume you woudl wnat another product - the only issue MAY be is if they specifically said you would get product B if products A wasnt instock and you accepted that.

And you are charging them 50quid a day for storage dammit!
Lawyer: Are you sure the man was dead when you performed your autopsy?
Doc: Quite sure.
Lawyer: How can you be so sure?
Doc: Because his brain was on my desk in a jar of formaldehyde at the time.
Lawyer: But is it not possible he could have been alive nonetheless?
Doc: I suppose he could be alive and practising law somewhere...
These are better, im(Factual)O ;P:
A new client had just come in to see a famous lawyer.
"Can you tell me how much you charge?", said the client.
"Of course", the lawyer replied, "I charge $200 to answer three questions!"
"Well that's a bit steep, isn't it?"
"Yes it is", said the lawyer, "And what's your third question?"
A client comes to Chambers for a conference and is told that her barrister has died. The next day she comes back and asks to see that same barrister. The receptionist says 'He's dead and you know that. Why are you asking to see him?' The client replies, 'I just love hearing it'.
OP: you must formally have rejected the goods. If you have:
(Sale of Goods Act 1976, Section 36)
''Buyer not bound to return rejected goods
Unless otherwise agreed, where goods are delivered to the buyer, and he refuses to accept them, having the right to do so, he is not bound to return them to the seller, but it is sufficient if he intimates to the seller that he refuses to accept them.''
^(and then the alarm would go off, and you would resume your more placid personality)
If you accepted the delivery instead of turning it away that might count against you.
Out of interest, who was the retailer? And was it an online purchase?
The goods are not fit for purpose, you are entitled to a refund.
The goods are not as described, you are entitled to a refund.
NO IFS, NO BUTS!
