Fresh Air Care; Douglas Alan Rohm charged for equipment and services not provided or done correctly. Refusing to repay. Columbus, Ohio

We called Fresh Air Care to have our air ducts cleaned because our son had thrown toys down an air duct in his room and to have the furnace cleaned. They said there was mold in our furnace and that they had to treat the furnace before they could clean it. We agreed to the fumigation and were told the total for the cleaning and fumigation was 559.00. When I originally called for pricing it was going to be 40.00 to clean the air ducts and 99.00 to clean the furnace.  Later the business came back to clean the furnace and then charged us an additional 283.00 to clean the furnace and air ducts.
At this time we looked closer at the invoices and saw that they had charged us for a UV lighting system for 299.95. I looked up what this was on the internet and looked at out furnace for this thing and it was not there. We called another furnace cleaning business the next day to confirm that there was not a UV lighting system installed and he did not see one either and we payed him 40.00 to come out and look things over.

While he was here he pulled out the filter from the furnace it had chunks of dust and stuff on it. He told us if they had cleaned the furnace properly there should not be chunks on the filter because they would have been sucked out. He also told us that because our furnace is not even 3 years old, has been used continuously since we moved in and our basement is not a wet basement that there is a very low probability that there was mold in the first place.
They also charged us 110.00 for treatment of air passages with sanitizer along with the mildicide for 150.00 before they cleaned (this was the fumigation). After they "cleaned" the furnace and air ducts they recommend we sanitize the air ducts. We told them we had already payed more than we had planned on spending and at that point we had already paid them 559.00. They said they would do it for free then. I don't understand why you would even put the sanitizer in before cleaning the first time then. Then they asked how we wanted to pay for the cleaning.  This is where the 283.00 came into play.  

To top it all off, the toys are STILL in the air duct. They told us the first time we asked about the toys if they would be able
to get them out and they told us their equipment could suck a bowling ball out of an air duct, so why the rag doll made of one piece of fabric and a small wad of cotton is still in there I don't know. 
So we called to tell them we wanted our money back for the UV light since it wasn't installed and they never talked to us about it.  They said that it was on back order and thats why they didn't install it yet and that since they had ordered it that we couldn't have out money back. They never told us or asked us if we wanted it AND they never told us they were coming back to install such a thing. We also talked to them about the toys in the air duct and they said they would have a manager call us back that day. No one called and when we tried to call back around the time they were supposed to call back the phones automatically went to a technicians voice mail.  We have been trying to call ever since without return call. 
Don't trust this company.  Don't let them in your home.  We learned the hard way not to go for a deal out of the penny saver.  Hope you read this before your the next target.
