Having problems returning items due to the current situation. Been trying for weeks but the QR codes are flagging up as already used in the post office. I have spoke to a couple of people as ORG52 (via messenger & chat) who were not able to solve the problem (one simply ended the chat with me; perhaps it was an accident). Christopher, who I spoke to today told me to try Hermes, which I have done. They collect the parcels tomorrow. So fingers crossed, they are able to take them with no problems. So, thanks Christoper.
