Voltas — Service related

I have logged complaint on [protected] for ac repair. Service technician came checked and informed that some circuit need to be replaced. I gave him 350 INR for service charge. Now when i told him to repair tge circuit which cost around 9000 as per technician. Now technician is saying that i have to log another complain which again cost me 350.
And when called customer care [protected] they are saying they cant help.
I request please don't try to steal our hard earn money and please don't torture us.
