Told work was slow and he could not use me anymore and then after 3 weeks I filed for unemployment and he is denying my claim by telling lie's

Let me first say, I did not quit nor resign from my position and that is the lie he is telling unemployment. I have several witnesses to the fact. We had our house for sale and the buyer was unable to obtain a loan and they defaulted on the contract. When I called Dr. Bartels he said no problem and come to work on Monday June 3rd. At the end of my shift I was told that work was slow and to take an unpaid vacation and beginning on June 17th I could work from 9:00am to 1:00pm Monday thru Friday. Although it was not my regular full time hours I was appreciative to have those. Then on June 17th when I called Dr. Bartels I do not know what changed but I was told the Solon Veterinary Clinic no longer needed me. I do not understand why Solon Veterinary Clinic can refuse me employment and at the same time are trying to deny my unemployment option as well. If they do not have work I understand that is why I filed for unemployment until I find another job.
