cross check

Can I be jailed if a company offered me a service of writing several postdated checks for furniture. all of which were cashed except for the last one bc of an on the job injury in which Ive been off work for for 4months. They are calling me saying im ignorant for writing the checks and that im a criminal and I will be prosecuted by the DA's ofc. Can they do this even if I tried to set up a payment plan with them but they refused it?
