Bosch Home India — Washing Machine Defective; No respite despite multiple complaints

My Bosch washing machine is defective and is causing damage to clothes. I have complained multiple times in the past, but the problem never got resolved. Infact despite requesting for senior technicians they keep sending the service request to the same outsourced agency in our area. The staff of that agency have tried to resolve the problem multiple times in the past and have failed despite charging for part replacements and service on multiple occasions.

I have already paid over 3K till date but without any resolution of the problem. I am not willing to pay anything additional now for a manufacturing defect. In fact, the service agency at one point started to cancel the appointments automatically as they did have any solution to the problem.

I believe the software programme of the washing machine is faulty and now the machine has started to behave in a random fashion even for the preset washing modes (sometimes does not spin; sometimes does not rinse, etc.). Need inhouse experts of Bosch to fix this.
