Business ProfileforLogo Infinix

I purchased a logo designed for myself from Logo Infinix in 2022. We agreed on a set price of $175 for the logo design, unlimited changes, and once logo was approved they would send business cards and stationary which would complete transaction. When logo was approved, they refused to give it to me without filing an additional trademark of $1500 which was not agreed upon at the time of purchase. After an hour on the phone, they finally agreed to give me the logo and files, but refused to send the cards and stationary that was agreed upon.A few months later, I was contacted by Logo Infinix and was told that another business had filed for a trademark using my name, and that I would have to pay them $500 to have Logo Infinix start a trademark file for me to cut the other company off. I paid the $500 (now totaling my purchase with the company to $675) and asked for proof that the filing was done. I never received proof. In July of 2023, I was contacted by ****************** of Logo Infinix and was told that I needed to pay $1000 more for my trademark to go through, but that if it didn't go through that all the money I had paid thus far would be promptly returned to me. I told them I did not have any proof of the initial filing and that I would need proof before sending additional money. No proof was provided to me, and no refund was issued.Since then, I have been contacted by no less that 7 other representatives of the company saying the exact same thing. When I tell them to stop contacting me because they are harassing me, the say I am giving them attitude and that they won't process a refund. This happens every 3 months with screenshots and emails taken each time as proof.
