Samsung India — serious issue with service provided

Address:

Kolkata, West Bengal, 700090

The above mentioned AC model was not working properly for sometime due to which I called the Samsung customer care exec and lodged a service request at my residence. They came for inspection on 22nd July 2019. After that they picked the unit from my residence. After that they came to my residence and to take the estimate amount of 9904 INR. I paid them that and they gave me the bill. Then they came to my residence to install the "repaired" product. But during repairing one of the service men said that some problem is there and the unit has not been fully repaired yet. They need to take it back. They picked up the unit for the second time the very next day. I was confused because I have already paid the amount in full and still they said they it was not fully repaired. Anyway, I suspended my work for that day to send off the unit for a second time. After repeatedly calling them to inquire about the status of the repair, they said that they would deliver the unit back on Thursday/Friday of that week, but they actually delivered it on Saturday. I am a working lady and I missed two office days just because of their mismanagement. On Saturday, they came to install the unit but while installing they noticed that the holder for the indoor unit is damaged and that they "conjectured" that this must have happened during transit. I was thoroughly disgusted by the fact that after so many days of keeping the unit with them, they have to take the unit twice for repairs and they also damaged the indoor unit. After that they came up with a temporary solution of fixing the damage by using a screw to hold the unit in place. They drilled up a very visible part of the indoor unit and adjusted it with a screw. After I pressed them further, they said that Samsung company has told them to attach a screw in case the holder gets damaged. Needless to mention, I can clearly make out they they were lying.
Now, this is my question to the Samsung customer care. Do you really think that after spending 15k on repairs for the unit, I would expect your servicemen to damage the product and make it look ugly? The entire bottom part of the unit looks weird and people visiting my house are questioning how Samsung can ruin the aesthetic appearance of the indoor unit? Why do I need to put up with the lacklustre attitude of the customer agent and suspend work just to honour their time commitment? I need answers. I don't need an apology. i need real tangible results. I am attaching the pic of the damaged part. Again, I hope this gets resolved here, or else I will be going to the consumer court for the damages.
