I have a Ford Focus that I sent to a local Firestone for
repair of a flat tire.  They advised replacing it with a
snow tire.  They also said I needed $700 work to tune it up.
So I paid the $$$.  A few days after driving the car off,
I got another flat tire.  So I sent the car back to them and
asked them to repair the new flat tire.  I paid $150 or so
for another snow tire.  I went back to drive the car off
again.  As I was driving home, I got another flat tire!
When I got home, just 1/2 a mile away from the Firestone
place, it seemed like there was a baseball-sized depression
in the front tire.  I asked them if maybe they did something
to the tire that might have cause it to have a flat.  They
said no.  I paid another $150 to get another tire.  Is it
possible they ripped me off?
