Went in for an oil change on Tuesday and had a discounted price on my phone mail for a $99. Price. They said it would take 2 hours well it took over 4 hours and when I got home I checked my e mail and their price on my phone mail for a $99. Price. They said it would take 2 hours well it took over 4 hours and when I got home I checked my e mail and their was another coupon from Diamond for an oil change for $49. Dollars. I went back and asked the manager to honor that price and he refused to because he was not aware of that coupon. You would think that any price reductions that come from their company the managers would be aware of. More

Took my truck in because it was inoperable but after your diagnosis your team “iris” said it was a battery fault, I believed her and had my daughter pick up my truck to bring home. Next day (today) I drive i diagnosis your team “iris” said it was a battery fault, I believed her and had my daughter pick up my truck to bring home. Next day (today) I drive it to work or attempted and I completed stalled and had AAA come to assist again. Took into another shop 50 miles away and they said it’s not a faulty battery. So here I am again attempting to get it fixed because the place I bought it from was no help and service was horrible. Mid diagnosis. I will be going public with this type of service. You risked my daughter’s life and mine. More
