Rarely use EBay and have never experienced this.
Listed a heavy electrical item as Collection Only.
Accepted an offer on Friday.
Buyer has not paid and was paying on collection.
Buyer said he would come yesterday and collect. Didn't show up. Didn't respond yesterday to messages giving directions. Has not responded to query if he still wants it.
I have heard that raising a case with EBay often backfires on the seller though?
Am I OK to cancel and relist
