S & D truck springs Sold me the parts that don't fit my vehicle and will not give me a refund

I bought a air ride suspension from SD truck springs on line when I went to put them on they did not fit my RV I called the company and they said they needed pictures to see why they didn't fit my RV . I sent them pictures they sent me a e mail saying sorry we can't help you.

We have never had this problem. Before again sorry for the inconvenience. But no refunds were offered to me only sorry we sold you the wrong parts but we don't care about your safety or that we sold you the wrong parts as long as they made money is all they care about.

I'm not a Rich man in fact I'm on social security and that was a lot of money for me to spend. On parts that don't fit . Hope their happy with my money. Because I am not happy with their parts or their customer service . They car only about making money . Not the customer that comes to them for help.
