Business ProfileforLeChat Nails

I am a nail technician working in *********, ******. On August 31 of 2021 I ordered $2913.17 worth of polish from LeChat Nails to start my small nail business. When I first received the polish I also ordered a pre-painted polish palette to show clients all the colors I offered. Some colors on that palette were not accurate to the polish so I repainted them thinking it was a simple mistake. In April I started noticing the polish fading on my clients after about a week. On April 20th I contacted LeChat support and started corresponding with ********* about the fading polish. For months I got no answer as to why the polish was fading. I had a list of polish colors I couldn't use on clients. I decided I wanted to do a return on the entirety of my order. I no longer trusted the quality of the polish. ********* assured me over phone that I could do a full refund and that they would pay for the shipping of all the polish being that the polish was defective. As a nail tech I can't take clients without polish to paint on their nails. ********* was kind enough to give some time to order entire line of polish from a different company to replace all the LeChat polish I had. I would have not order $3900 of polish from a different company if I had not been able to get a full refund. After I ordered and received the new polish I told ********* that I was ready for the shipping label. For weeks she didn't send me the shipping label and is now telling me that they will not pay for shipping on the entire order but for only the defective polish. Soon after that the president of the company contacted me and is now telling me that they won't do a return at all but are willing to do an exchange for the amount of the defective polish. Attached are all the corresponding email between me and ********* along with the email the president of the company sent me and my response. Emails may have jumps in between because that would be when I called on the phone to talk to them personally.
