Anyone used Vintage Cash Cow to clear old stuff

Had never heard of Vintage Cash Cow till reading the Sun newspaper this morning, there was a letter from someone saying they had sent them two big parcels of various stuff a bracelet, gramophone, carriage clock, pocket watch etc They were told the gramophone was worth £29 The seller asks for the rest of the stuff back but Vintage Cash Cow wouldn't send the rest back they said they don't do part-returns when the item is under £50.
Mel Hunter from the Paper who fights for your rights on behalf of readers said they couldn't get the stuff back but did get £200 compensation, so guess I would be careful.

I’d be really careful with this. I’ve read about items being seriously undervalued, so it depends on whether you know what the stuff is worth before you sell it.

Yes I did once a while back and I wasn’t happy with the valuation at all I d never use them again

I'd rather take things to charity shops than fund a commercial venture.

Thanks everyone. I may give it a miss.
