GXI Z-beast trying to get a refund for my zero turn mower Clayton North Carolina

I purchased the 48 inch zero turn mower in April of 2018, had n othing but issues with  throttle breaking, support to deck and no power.  they sent wrong parts 3 times and when I complained about no power they told me to read the booklet and figure it out.  I couldn't take it any more this year, I had them pick it up and learned that both transmissions needs to be repalced,  At this point I am done and just wanted my monies back.  Can not get anyone on the phone to help me.  all I get is 1.  go to this site and fill out a complaint, still no answers.  when I want to speak with someone, I am told that the customer service people have no access to management, they would email them.

been dealing with this for a month and no resolution.  I need to find an attorney to assist.
