Firestone Complete Auto Care review: lifetime alignment and balancing contract

Re: Date 3/12/2016 Store #: 020516 Firestone Complete Auto Care, Lakes, 930 Baseline Rd, Tempe, AZ, 85283 Invoice#: 240935 ; Service Advisor: 02 Jerrod; Technician: Louis Ph: [protected]
On 3/12/2016 I brought my car in for an alignment and balancing check. My appointment was for 5:30p.m. but got there at 4:45p.m. to check my car in. I was told that my car would be ready at 7p.m. that evening so I left. Upon arriving at 6:50p.m., I noticed my car was still in the bay. When I asked the sales person about my car still being in the bay, she replied that as soon as the technician drove it out, I would be able to check out. At 7:00p.m., I noticed that my car was now being driven into another bay. I flagged the sales person again to find out what was going on and after she checked with the technician, she came back to tell me that it was only then being checked for the alignment and that it would take another 20 minutes to complete. I informed her that I was not happy as I had left the car early for the appointment and that the previous time that the car was worked on, I had to return a second time because to pick up my car because they were about 2 hours later than they promised.
I have been a loyal customer of your throughout the years. I believe I have had at least 4 cars (maybe 5) under Firestone's care for about 20 years.
When I brought this to her attention, she talked to the technician who said he'd work on it immediate. At 7:05p.m. I saw my car being driven out of the bay and was told that my car was done. Puzzled and suspicious, I asked her how my alignment was. She replied that it was fine but that the printer didn't work so I was not provided with a print out of the alignment. I, thus, have no way of knowing if there actually was an alignment check performed.
My question is: Can you do an effective alignment check in 5 minutes? Also, in all the years that I dealt with Firestone, I never had the printer fail. Is this scenario acceptable by Firestone's standards?
I am requesting that someone contact me to let me know how this matter will be attended to. In addition, I am also requesting that a recheck of my alignment be performed immediately upon my arriving, without having to wait in line for my car to be checked as I have already done that.

P.S. In previous years, the service at Firestone was exemplary. I am hoping that it can return to that level of service.
