Bosch cannot provide input on their own products

I am greatly disappointed with Bosch and their non existent knowledge on their own products.

I've logged an online ticket at Bosch: Ticket# ********** ********** 21231 on 17 August 2017. "Dear Reader, Trust you are well. I am looking for a Rear Parking Sensor which will work as a replacement for Bosch Parking Sensor (Bosch Ref #: ***/ VW #: 1J0 919 275), which can just be fitted from the outside of the bumper. In other words the parking sensor should not be "L-shaped", just just be "I-Shaped". Please advise on the available options. Thanks in advance. Regards Wynand" I hace received answers such as go to a Midas...this is so disap****ting, when you are asking the manufacturer a technical question on their own product, they refer you to the reseller...what would the poor reseller know about the technical compatibility of their suppliers products??? This has just spelled it out to me that Bosch does not know their own products and just wishes to send you on a wild goose chase not giving you amy form of assistance. This is complete consumer abuse.

It would be appreciated if Bosch can actually look into the above ticket and provide an relevant answer that would actually assist on the inquiry raised.
