Anyone buy a bicycle seat recently in SATS in Benemar

Hello. Bit of a long shot. Did anyone recently buy a black bicycle seat mounted on a black square seat post in the last week or so?

It was inadvertently left at the SATS charity shop in Benimar and appears to have been sold. I really need it back because the seat post will only fit my exercise bike and I can't get a replacement!

If the buyer sees this message or knows who might have it, could they please get in touch by PM or email.

Many thanks

Anyone?
