The Pep Boys

I had my ford excursion towed to pep boys at 3019 Allison Bonnett Dr Hueytown Alabama because it would not start I thought it could have been battery or alternator problem on March 19 and they told me that they were very busy and could not get to it right then so my vehicle set on their lot for two weeks before they looked at it, they called me and said they had gotten it started they were not going to charge me for it because they couldn't find anything wrong with it but when I came to pick it up when I cranked it up it was very loud someone had taken the catalytic converter off of it.
