Seller threatening me and not issuing refund .

I bought a shirt from a TikTok seller and immediately regretted it so I tried to cancel the order which was denied. I then waited until the shirt got to my house so I could take it back to the post office to ship back so I could get my refund. Took it back took about a day to get there. Mind you seller has declined return and refund twice already and then when they get the package they claim that it's damaged which isn't true. The shirt in question never even touched the wind outside. Long story short I leave a bad review and seller starts threatening me and sending me my personal info below. (bro didn't even get the right house on the last slide) I just want my refund and for this shop to get banned 🤦‍♂️ I’d rather buy off of fuckin Temu and shein
