Hymbas LLC Diann Keller advertise a 60 day return policy but when I went to return they said no because part of it was on a lease boca raton florida

I ordered a BCX Rife machine from them I put 1,595.00 down and a 1,000.00 on a lease when I went to return it they said I could not because of the lease, but the lease company says I can, I also never recieved any sales paperwork from them ony what the lease compant sent for the 1,000.00, now that I have threatened to sue they will with a 15% restock fee, but no legal paperwork thats says they will, Diann says she has been doing this for sixteen years and was always told she could not cancel lease, hmmm sixteen years? you should know the in and out of a lease, and according to records she has only been in business since 2014
