In September Mrs. Looknee had over £400 taken out of her bank

so cancelled her card etc
At the end of September had a knock at the door, so answered it and a delivery man was there needing a signiture for the parcel he was holding which was addressed to Mrs. Looknee, so I signed for it thinking she had bought something for Christmas.
She opened the parcel to find two Brand New Nokia N97 phones :-? which neither of us had ordered. The following day a letter from Vodafone came telling us what contract "We" had, which was £98 per month for both phones

So I got on the phone to Vodafone to explain there has been some mistake.
Around 20 phone calls later (each for about half an hour long) and not a single reply.
So on the 2nd of October I wrote a letter to the Managing Director of Vodafone with all the dates that I have phoned, explaining that I have not recieved a reply at all etc.... about the two phones that we have here...
And still no-one has contacted us to pick them up :-?
I have been telling Mrs. Looknee to sell the bloody things as I can get £500 cash for the pair of phones, but she won't....
Would we get into trouble if I did sell them?
How long is it until they become ours?
Should they be compensating us for all the phone calls made, time wasted etc??
Any help appreciated
