A mate was burgled and lost several grands worth of electrical equipment. Insurance paid out, new locks fitted etc etc.
6 months later, police come over with all his stuff that was found in a property that had been raided (it was etched with his postcode etc).
he ran the insurance com[any who said they'd arrange a courier. 9 months later having heard nothing he put the whole lot on ebay and bought a high end bike he never uses. I'd say it is the companies responsibility to collect their goods, however, from their point of view the cost of collecting an unsaleable item might be great enough to just "dump it". However, if they admit this to you, everyone will start damaging goods delivered and getting 2 for the price of one, so they just ignore you and hope you take the innitative!
at least that what I think!
