Business ProfileforAirgas USA, LLC

I leased/rented the smallest cylinder of ************ at **** psi for HVAC purposes and returned the cylinder according to the terms of the agreement/contract. The cylinder did not have a hydro date and was originally damaged.Later, it was noted by the individual behind the sales counter along with my spouse that the cylinder was returned to the store.The Airgas Store representative who I originally purchased the N2 gas and rented/leased cylinder from last week asked me to return the cylinder to their designated area outside instead of in their store.I carried the bottle to where another Airgas representative was gathered with four large welding gas cylinder and other customers on the loading dock. He pointed to a suitable location to leave the bottle. I asked about refills where he said they did not have any N2 available which agreed with the sales person inside the store. This almost ended the N2 cylinder gas transaction except the return of my large deposit and a reduction and the return of an overcharge on hazmat fees.It was noted and brought to the attention of several Airgas administration that the attached documents contained altered and/or incorrect information along with my deposit and reduction in fees not credited to my card. A police report was filed for fraudulent use of my credit card as I did not authorize her to keep my funds.In a separate and new transaction I had an account opened at the busy Airgas Store in ******* where I purchased more N2 gas and was out the door and on the job quickly. To this day I never received the deposit and the hazmat fee overcharge credited to my credit card account.I wish it to be returned along with interest immediately.
