Firearms Unknown interview questions

Received a call from Mauro about an interview. Came by around 11 and got my Interview. Understood it would develop to a GM position to which I agreed. We discussed pay and what I would would be. Being very low but good experience to gain I agreed. He then asked me to get livescanned and begun the COE process. I went and got everything done and paid $100 out of pocket. I let Mauro and he then offered me a job the following day $2 less than what was discussed. I let him know what mu bottom number was and he said he'd get back to me. I thanked him for the offer and asked he let me know what the outcome was. He never returned my call or let me know what was going on.
