Shell

I got $12.26 of unleaded gas from this station on sunday 07/07/13. monday drove to work, leaving work my car died at a stop sign and wouldn't start. I had to call a tow truck (cost $119.90), to take my car to lute riley honda to flush out the watered down gas from my car (cost $440.41). then I had to get a rental (cost $109.60). I have all the receipts.
The manager wants me to meet him face to face?. all I want is to be reimbursed for the gas first, then the car repair also. he keeps telling me his gas is good he has checked it.
What do I do? I need help please. I will not meet him by myself!
