Hi I hope someone can help me . I had an item for sale which a member asked if I would post to Canada which I was happy to do so if they paid postage. By the time I had a reply someone had bid in my item so couldn't change settings to international the member began messaging me that I saw they next day due to time difference 8 messages . I replied and explained that unfortunately someone had bid therefore couldn't change settings apologied and thought that was it. I then again over night had another 6 messages getting more threatening telling me to contact the buyer and say they can't have it it's theirs that I'm a scammer and demanding that I send them and invoice to pay and post to them . Again I apologised and explained that this was unfortunate but was sold to the bidder that won and I couldn't change. Now I have had another 8 messages threatening again demanding that I contact other buyer and send to them otherwise they are going on all social media to rubbish my name and reputation. What do I do ??
