SELLER LEFT THE WRONG MESSAGE ON MY FEEDBACK AND IT LOOKS LIKE IVE DONE SOMETHING WRONG.THEY WANT TO CHANGE MESSAGE TO A GOOD COMENT BUT HOW DO THEY DO THAT?
ive had 2 parcels go missing through myhermes,before i would contact them and they would sort it out.now because ive booked through ebay they said they cant help.trying to get through to ebay takes so long,why dont they have live chat or an email you...
TODAY WHEN LISTING AN ITEM ITS GONE BACK TO AN OLD VERSION AND TAKES AGES TO LOAD PICTURES,WHY HAS THIS HAPPENED AND CAN I SWITCH BACK TO THE NEW ONE?
