MisterautoReviews 

Doesn't seem like Mister Auto have rectified their customer service problems. Wrong parts sent as a replacement for the parts they didn't have in stock (but the website still claims the parts are available). Poor customer service and a refusal from the supervisors to stand-up to the plate. I mean, who would want to speak to an unhappy customer and help them out? One big mess all round and I will not be going back.

Total waste of space. They mess up and blame the customer

Please refer to my previous review and Mister Auto response
The only thing worse than wasting time and money on wrong parts is blaming the customer for choosing wrong parts or perversely their own websites facility re reg number.
"Kindly be informed that the license plate facility can unfortunately not recognize the exact year of construction of your vehicle. During the construction period the manufacturer may have changed some of the parts for the certain model, there might even be two parts for the same year vehicle, and this is why a part listed to be compatible may not fit as it is for a newer or older vehicle than yours.

Kindly note that the product that you ordered is not for vehicles with a sport chassis, but for ones with a standard chassis as stated in the product description."

This seems to be the stock reply and it totally untrue -
The website using reg number offers only rear springs for sports suspension in the product description copied below
For your MERCEDES-BENZ C-CLASS (W203) C 220 CDI (150Hp)
Coil Spring BOLK BOL-F011027

Those could well have been fine, had they delivered them, but they sent springs for an E Class estate, a completely different vehicle.
The remedy was not possible because they had been fitted, so l was stuffed and left to bear the expense.

This shows why l had to give up trying to get any sense of responsibility from Mister Auto.

AVOID Mister Auto.
