[Resolved]  Voltas — Service Delay/ Money Fraud

This is regarding the constant problem that I have been facing from the past 15 - 20 days. My service request number is [protected] . The quality of the service done by the engineer is pathetic this time. On the first visit, engineer came and told us that the condenser coil needs to be replaced. After waiting for 10 days and constantly calling, the engineer came to replace the coil that cost me Rs 2000. Even after this, ac was not working. On calling him again, he then said there was an issue with PCB and it would cost even more money (Rs 1500) to which I agreed. Now today he came and fixed the PCB but ac is still not working, he has marked the request resolved but i am still facing problems. I am fed up of calling him again and again and him doing nothing about it. To say the least, he has worsened my ac condition. It has now been 15 days and the engineer coming at my place is not trustworthy and trained to fix my issue.
Also I came to know that the parts that he fixed/replaced were under warranty but they still took Rs3500 from me and gave me a fake job report stating that this is the bill of 1500. I constantly asked for the bill of condensor coil that cost me Rs 2000 but have still not received it. I request that strict action be taken against such brands as they take advantage of customer and mentally harass them.
I want strict action taken against Voltas and my Ac be fixed/ replaced along with the amount that was taken

I am also attaching the constant mails that i have been getting from them that issue will be resolved but still no action taken.
