stealing from business clients nashua charged me for a machine that does not work

i signed up for a digital touch screen machine on rent to own from Nashua South Coast, since the first few months of signing the machine nashua south coast didn't have ink , this cost my company huge losses as we had canceled training I eventually stopped my debit order and asked nashua to uplift their useless machine and they couldn't keep stock nashua then decided to offer me to keep the machine because I want my full refund of all my rent to own payments, nashua south coast still bills me for their machine and I don't want it , I want my full refund for my machine and a payment for all my business losses I lost over 118 000.00 with cancelled trainings. Nashua I want my monies , monies don't grow on trees
