Whirlpool India — Whirlpool Washing machine Sound

Hi Team,

Last month, my washing started making krrrrr sound while washing clothes, so i called the technician from authorized wirlpool service center : M/s Active Enterprises. The Technician said, that a sensor motor need to be change along with Bireat Operator. I agreed and while installing the parts, he opened the whole assembly of the motor along with the main motor and side motor. He even used a hammer to pull the mail motor from the drum.
Now after 1 month, the washing machine started mail the same sound again and now the technician is saying that a gear box need to be changed which is going to cost me 5000rs more. When i showed him the last month bill, he is denying that, earlier work is different from this issue, so no warranty/service and i have to pay the amount.
When i asked him, what does the gear box do, he explained me that gear box pully is attached to main motor which make the washing zigzag.
So that means last technician, when he pulled the complete assembly out and did not put it back properly, because of which gear box is not working properly.
But Active Enterprises is not ready accept the fault.
Please look into it. It seems the last service has worsen the issue.
