Fraudulent seller disputing negative feedback and harrassing me to retract

[simabgm]

Hi sorry this is a long one...i won a designer item at auction for £77 and paid for it straightaway. The seller marked it as dispatched the next day then a couple of days later said the item is damaged so can't send out.
I asked for pictures and said maybe i could get a partial refund if i'm still happy to take it. He refused to give pictures and said there wouldn't be a discount as the item was already priced well below the price he wanted. When i asked for pictures he told me he would relist the item! After a lot of to and fro i decided to accept his offer of a refund.
I left negative feedback because i didnt want someone else to go through the same ordeal because it was actually very stressful for me.
A few days later he asked why i left negative feedback saying he is a new seller and he thought it was defamatory. Once i explained why i left negative feedback he asked if i could take it off if he sends me the coat (which was relisted without any damage btw).
I said yes i would if he could rectify the issues but send it through recorded delivery.
He disagreed with that and said he would drop it off to my address (which he obviously got through my earlier purchase)
I then noticed he has relisted a couple of other items that were on auction last week that had also been sold. He also put a few BIN listings of £200 with blank photos presumably so he could utilise the max £1 fees.
So i definately don't want the item now and all these things make me think this seller is fraudulent but I'm feeling a little bullied into retracting my feedback especially since he's very quick to come to my address.
Any advice?

Why would you want to change the feedback? You had a negative experience so let the  feedback stand.

Put them on your blocked list because you are also a seller and you don't want them buying from you.
