On marketplace I accepted verbally an offer to sell a piece of furniture for £***. I had not received a deposit and have dealt with many time wasters before not turning up to collect items. A different person was interested in the same item and they offered to pay me full price £*** and come and collect immediately. I agreed to sell to them so once they had collected the piece of furniture (mirrored cabinet) I straight away messaged back Tracey and apologised that it was now sold to someone else who had offered the full price. I then received a string of abusive and threatening messages from her. She has threatened to warn others on selling sites with my picture from my profile. she then threatened to report me and finished with "Have a great life". I am extremely worried now especially as she knows my address. I did not have a contract to sell to her and she said she could not afford more than £***. Please can you urgently look into this as I feel threatened and will have to report this to the police if it is not taken seriously. I urgently need my account re-activated as I am moving house in two weeks and am trying to sell off as many items as possible.**Kind Regards**Lisa Hine
