Onida / Mirc Electronics — front loading fully automatic washing machine

Address:

500081

Hello, i have been using an onida fully automatic front loading washing machine since last 2 years.
In the month of december 2019 the pcb board was out of order, on 26th december i gave a service request to replace the same. As confirmed by customer care i agreed to pay the price as it was out of warranty.
After waiting for 15 days the executive came to my place with a used pcb.
When i argued and took a photo of the same, he said he will get a new piece for me.
Days passed and my follow up continued.
When i told the whole incident to customer care they provided me the service manager number for hyderabad.
I have called him 10 to 15 times he responded only 2 to 3 times, each time he says i will check and get back to you.
When i was able to interact with him for the first time and complained about the executive trying to sell me a used pcb, the service manager said if your product is out of warranty you will get a refurbished pcb only at the original new price.
I said ok get me a new one

It has been 1 month neither customer care people nor service centre people are able to solve it.

Every time customer care people keep on escalating with a promise of callback which i never got and service people dont pick my call at all.

In this case i am suffering just because i caught them redhanded while they were doing a fraud.

Please help
