seller refunds one day after sale no explanation, no note, email nothing.

[activar]

You folks have helped me through all the hoops to enable me to make the for purchase a much wanted keyboard for my studio yesterday and i just received a email from paypal informing me that 123 music refunded my purchase, I had been in touch with them via email about details of items condtion, concerns about shipping ect before i made my purchase and they responded with all good. I'm not hard to get along with but seems like they couldve at least sent me a email and explained why they refunded my purchase or put a message in the box left open in the paypal email for note from seller, I have never had refund without an explanation,  Thanks,

You have to ask the seller,it is not uncommon seller cant find the item,either lost or sold already.

if it were an auction,could be the higest bid $ is too low or too difficult or costly to ship
