Castrol Premium Lube Express

I bought new tires there last week and got home and had a flat tire. I took my car back out here and they said it was the valve stem and they “fixed” it. I purchased the tire because I was driving to Florida that weekend. I got to NC and had a flat tire. I took it to SAMs Club and it turns out that castrol didn’t not put all the pieces back on my valve. They left a very important piece off and I was stuck in NC for 4 extra hours with a 2 year old and an 11 year old who needed to be return home at 730. They’re carelessness could have got someone killed if that tire had messed up on the interest. I would NEVER recommend them to anyone!!!!!!!
