Business ProfileforRNR tires

I had purchased tires and an alignment, to which they provided. They told me my outer tie rod was broken, but it was just the grease membrane that was broken. A couple of months go by, and I noticed a loud sound coming from the driver side front tire. The front driver side tire had been disconnected from the outer tie rod causing the tire to point inward while the passenger tire was straight. I looked under the truck to see that they left the locking nut loose causing the outer tie rod to lose the threads and disconnect from the inner tie rod. I had to personally replace the outer tie rod and get an alignment to fix the problem. I told the manager ***** about this and he offered an $80 discount off of the $955 that I owe for tires. I told him that the offer wasn't good enough. I sent an estimate to ***** quoting $22.11 for the tie rod, $142.74 for the labor (which is the median cost of 1 hour labor in *******), $100 for the inconvenience, $130.57 for the alignment. This tally would take the total owed to them ***** $955 to $540.54. He replied to this email stating "Then we will just need to return the tires and part ways." I believe what I am asking for is fair and am not looking for anything "free".
