We ordered parts on 1/18/18 (Thursday)to be delivered by 1/19/18 (Friday). Paid a premium of $ 350.00 for the express service. Got an email confirming delivery. On 1/19/18 parts were not received and tracking info had been changed to delivery on 1/22/18. After several calls to FedEx on Saturday morning found an individual that located the parts two hours away in a shipping depot. They were scheduled to be delivered on 1/22/18. We sent someone on a two hour trip to pick them up from shipping depot. Only 2 of 4 parts were there. Filed complaint with RockAuto they said they would not refund shipping charges, in fact they were going to charge us for 2-day shipping and refund us only $ 92.00 of our original $ 350.00 overnight shipping charges because they say the parts were "Delivered". They were not delivered we had to pay an employee overtime rates to drive two hours to facility to pick them up. Even then only 2 of the 4 parts were there.
