Terrible customer service sent me the wrong items ...

Terrible customer service sent me the wrong items by the time i realized it was halfway on the vehicle now i have to send it back and then wait 3 weeks for my item to be in stock. Management wont get on the phone and discuss my issue with me everything was relayed through a customer service rep... i wasted my money on paying a shop to install the incorrect item they sent me i am out money and time.....
