Business ProfileforCamp Langston

I myself travel for solar construction work and own an rv. I always looks for locations that can offer month to month rates and are semi close to current work locations. A few people from the my current employer found camp Langston near ********, ** (where work was) that also own rvs. When I called the place a man named ***** answered the phone as the person who takes care of the location and owners are an elderly couple that live on the land. I asked how much monthly was and he stated $550 all bills paid. Decent price but he stated the catch is a refundable deposit of $550 to move in due to the area. We could do cash or debit. I paid with cash. I checked with other people staying there and they paid the same. Fast forward 7 months later the project was coming to a hold and I got transferred to Kentucky. I contacted ***** and told him Id be moving later that week due to just being notified and Id like my deposit and the two weeks money from the month I had just paid. He stated no problem and he would return the money. The day before I had to leave I messaged him again and asked where the deposit was? He then showed up at the rv the next day and stated he doesnt give cash back due to it being a business and he would have to make a check with their accountant. I was reluctant to allow this and asked if he could provide cash. He did not. But asked for my address to send the check, so I texted him and went on my way. Two weeks later I still had not received the check and contact ***** again. This time he stated he didnt get an address and I noted the address I sent two weeks prior And sent it again. Two weeks pass again so I reach out to some of the other campers who had left as well and he has done word for word the same thing. So I message ***** again and ask what is going on and he states the mail is slow. I have called the owner and she does not answer and I do not believe she knows he is doing this not only to myself but to multiple of my coworkers as well.
