Bosch Washing Machine - Washinng Machine massive voice while rinsing

I bought BOSCH **KG top load washing machine (WTL BOSCH WOA***X*IN BP**** MAYANK ARORA, CODE ****) dated **-**-**** from Sargam India electronics PVT LTD (Janakpuri West Delhi), initially everything was smooth going on but after that it started giving trouble, always it shows error as E*, E*, E*. At the top of all this, it gives massive sound as if something has fallen down from *th floor on the ground.

Many a times I have called the technicians and they have changed the part as well, still situation is the same. Technicians are also helpless, even SARGAM outlet is moved altogether to a different location.
I am washing the clothes today since morning and at this time it's **:** PM and the same lot of clothes are in the washing mode.
I got various errors and again and again I have to start the machine again, still my clothes are in the machine and they are not done till now.

Now I am also helpless and mentally tortured with this machines heavy noise and the ongoing issue since we bought it. I need an immediate resolution what the best can be done in this matter of concern.
