I ordered 2 wiper blades(11 23 2020 a day after I ordered plugs and wires(11 22 2020 they came promptly) for my car. I was informed that my blades were returned due to my address not being right by USPS...I would like to know why..and where's my money I prepaid? I will not be using rock auto again. Very angry customer.
