Godrej AC - Faulty AC and service

I registered a complaint through the Godrej IVR system on **.**.**** regarding my air conditioner, which was not cooling properly. The air conditioner is covered under a valid Annual Maintenance Contract (AMC).
A technician visited my residence on **.**.**** and informed me that gas filling was required. Accordingly, another technician visited on **.**.**** for gas filling. However, after inspection, he informed me that the cooling coil was damaged and required replacement.
Subsequently, on **.**.****, another technician visited my residence without carrying any spare parts and again stated that the cooling coil needed replacement. He assured me that the replacement would be carried out shortly.
Despite these visits, no repair work was undertaken. I repeatedly contacted Godrej Customer Care through the IVR system, but each time I was merely asked to wait for another two days. When I contacted the AMC representative on **.**.****, I was informed that the technician had failed to update the service status on **.**.****, and therefore additional time would be required.
Due to the prevailing heatwave, I suffered severe inconvenience, discomfort, and mental harassment, as I was compelled to follow up continuously with Godrej Customer Care without receiving any effective resolution.
On **.**.****, I again contacted the service centre and was informed that the repair would take another *–* days. When I contacted Godrej Customer Care telephonically, I was told that the repair would be completed within the timeline provided by the service centre and that I should wait.
Thereafter, I continued to follow up regularly. On **.**.****, I contacted Godrej Customer Care again, during which a representative of the service centre was included in a conference call. During the call, it was assured that the repair work would be completed on **.**.****. However, even by **.**.****, no repair had been carried out. When I again contacted Godrej Customer Care on **.**.****, I was informed that I would have to wait for another *–* days.
Finally, after continuous follow-up and repeated assurances, the cooling coil was replaced on **.**.****, almost one month after the initial complaint.
However, the air conditioner again stopped cooling on **.**.****. I immediately registered another complaint, pursuant to which a technician visited my residence on **.**.****. After inspection, he informed me that gas filling was required and stated that another technician would visit to complete the work. However, no gas filling was carried out, and the complaint was closed without resolving the issue.
Consequently, I was compelled to register another complaint on **.**.****. Since then, no technician has visited my residence, nor has any representative of the service centre responded to my calls. Although Godrej Customer Care executives have repeatedly assured me that action has been taken against the service centre and that the issue would be resolved shortly, no effective action has been taken and the air conditioner remains non-functional.
The conduct of the opposite parties clearly amounts to gross deficiency in service, negligence, failure to honour the AMC obligations, and unfair treatment of a consumer. Despite repeated complaints and assurances, the issue has remained unresolved for an unreasonably long period, causing me significant inconvenience, mental agony, harassment, and loss of enjoyment of basic amenities during the peak summer season.
I therefore seek appropriate relief, including immediate rectification of the defect, compensation for mental agony and harassment suffered by me, reimbursement of any expenses incurred, and such other relief as may be deemed fit and proper in the interest of justice.
