Business ProfileforE & J Used Auto Parts

I called ***** ********* used auto parts, as i needed a transmission. They said they had it and i purchased it 9/9/2023 in person. Before purchase, i offered the sale lady ****** the vin number and she said its ok, its the right one. I offered again and said are you sure? repeatedly and she said yes, so i purchased the transmission and started to mount it on my truck.. So NOW the transmission did not fit and it wasn't the right transmission. I called ****** and explained, she said there's nothing i can do about it. Asked to speak to manager and she refused to transfer me to him. I emailed him and left a review. he replied on the review and said we don't lie to customers, I can help in exchange for another one or we can work something out. After several attempts of emails to him, he never replied and helped out with my situation. During this time I had to repurchase the correct transmission from somewhere else. The wrong transmission sold to me is still in my possession and offered to give it back but no reply in return. The transmission purchased from them had a 30 day guarantee, which I reached out during this period of time. and still nothing was resolved. So I am looking for a full refund for refusing my emails and not working with me on the situation. I read the reviews on this company and learned that I wasn't the only customer that was ripped of/scammed over transmissions.
