Panasonic ac - Faulty product pathetic service

Due to lack of time sharing the mail body which I have shared with Panasonic. No revert received yet. I recently purchased Panasonic AC on *th May'**. Just *-* days after installation water started to come out of the indoor unit. However, this issue was resolved after long follow-up with the technician who came for installation. Needless to say during this period AC was useless.
Just when I thought that I'll use AC properly now I started to note that AC is not cooling at all. I was out for a week for official work and upon returning found that AC has literally turned into a fan. No cooling at all. On the **rd night, I raised an online request via R************ (As call centre was closed) and got confirmation that issue will get resolved in ** hours. Next day (**th May) as I got no update I thought I should call and confirm whether my online request is valid or not. Upon calling at the call centre I was told that my request is in process and I'll soon get assistance.
Next, I received a text that Mr Md.Mohsin Ansari - ********** will look into the repair of AC. I called at number shared in a text to my surprise this number was not valid (Same till today). I wanted to plan a visit to a technician properly so that I can be at home at that time. I called customer care again so that I can get the correct number of the technician. Customer care then again gave me a number of Mr Sunil who as per them will help me. I called Mr Sunil who told I need to contact customer care again as he is not designated service manager for my request. As I was one who was suffering I called customer care and again explained them my story. They gave one number of Mr Prateek. Again I called and got a reply that he is not a concerned person.
Please note that on **th only I called customer care * times and other service managers *-* times and wasted my **-** minutes in all this drama. Later in the day someone from Panasonic called me and asked regarding the status of my AC. I again had to explain the full story and was falsely assured that someone will come to my home soon. The day passed and no one came. Again one night I slept with non-working brand new AC.
Today is the day where I have lost my patience and presently don't even want to explain the whole story. Just note that same drama happened again and no one has visited yet (** hours) + passed already. Only today I got a number of new technicians, who again didn't turn up despite my regular follow-up. So, now that **k worth AC is just hanging like a box and I have already wasted my *-* hours asking for mere service of your defective AC, answer below questions -
*) How will you compensate for this harassment (Physical and Mental) to me and my family who have literally not slept peacefully even one night after AC purchase?

*) Now that I have lost complete trust over your service capabilities how can I get a refund for this box? I'll choose a brand which doesn't claim to be no-* in any county of the world and actually cares about the customer.

While you enjoy your Sunday, I'll wait and suffer, but note that very soon. If I don't get appropriate response from someone responsible person from Panasonic, my next mail will be most probably from a Legal channel, where I'll not request but demand action.
