I posted a parcel via Evri (luckily not experienced any problems with them before) on the 29th December. They tried to deliver it to the buyer on the 2nd and 3rd of Jan but couldn’t, not sure why. There hasn’t been any updates since the 3rd Jan and the tracking just says they will try to deliver it again on the next working day. The buyer has asked for a refund, but vinted said to wait until the 3rd of Feb to report an issue as the parcel might still turn up. Buyer isn’t very happy. What should I do?
