Firestone Complete Auto Care review: Back break shoes replaced

I left my 93 vehical to have new back breaks placed on my vehical following a front end elinement did the week before. The cost for this simple project has blown into a cost that can only be referred to as remarkable. I left my 93 Ford Ranger at 7:00 am yesterday morning and was contacted last night with a cost of nearly $600. Subsequently, contacted again with break in line and a further cost with labor and parts to something that was not even a problem to began with. I still have heard no news today and wondering if something else is going to come into play. My number is [protected]. Please give me a call if anyway possible. Thank you, respectfully.
