IFB Industries — looting customers by forcing me to buy pcb at an escalated price, instead of repair.

Address:

Hyderabad

I, syed ather [+[protected]], had raised a complaint for my washing maching ifb senorita aqua sx.
The machine was throwing door error even if the door was shut.

The technician came to my house today, 21st aug, 2020.

To my surprise, the machine's door error was not seen when the technician plugged it on. When i wanted to verify if it was functional, he hurriedly unscrewed the pcb. Later, when i confronted him, he connected the pcb again but the machine reported normal door error, not the issue i had reported.

I have following 3 complaints
1. The pcb board was forced upon me for an escalated price - rs 7, 650.
2. No attempt was made to ensure older pcb was functional or not and whether it could be repaired.

In total i was billed for rs 11, 130 as follows
1. Pcb board - 7, 650
2. Ifb stabilizer ivs 1804 a - rs 2980
3. Visit charges - rs 590.

I have a feeling i have been cheated by a forceful purchase and inflated prices. Kindly have a look and address my concerns
- can you confirm if my older pcb is functional?
- can it be repaired in case of minor fault.
- is the price of rs 7, 650 appropriate for pcb?
