Urban Clap - AC Service and repair

Last year we have refilled the AC gas , but it was leaked within a month or so . now we have decided to go with UC thinking it could provide us with better engineer and with concrete solution .
*) This year Feb ** , **** . we have booked an UC - AC Service and Repair service.Service engineer visited and confirmed that there is a leakage and took the outdoor and indoor Unit for testing the gas leak .
*) * days later he called up and said that Outdoor unit has a leakage and i need to replace the coil
*) we agreed to that and he replaced the copper coil and confirmed that everything is rectified and there are no other leakages
*) he came and fit the AC and filled the gas and tested - cooling was not that ok , but he confirmed that after a while it will be ok ( charged **** rs )
*) we started using the AC from Mid March .though there was no instant cooling , but it was working fine and lasted for * and */* month , then started the problem . cooling was affected and slowly water was leaking .

So again on May *st we have a raised a complaint in Urban Clap , and same engineer was re assigned .

*) he visited and re checked and told me that gas was fine ( with checking with the gauge ) , but he need to refill the gas as outside temparature is High .

*) later he said that R*** gas is unavailable so we need to wait untill he get that

*) on may *th or *th , UC executive and service engineer both confirmed that GAS is available and will be filling it by tomorrow _ after that niether UC nor service eng called , i have called many times but Service engineer never picked my call

*) on may **th i have raised a complaint , and got a call from UC . i have asked to stop the work and repay my amount back . as they are not providing any service but no responce

*) again on May **th i have raised the complaint , UC said that since they are not able to get hold of service eng , they have asked me to book a new complaint for imediate assitance and they will refund the new booking amount. and i did the same , since it is urgent for me .

*) new service eng came and confirmed that there is a gas leakage and left - charged *** rs ( UC never refunded this amount )

*) again the compaint raised , they siad that as gas is not available we could not complete the Job , i was very frustrated but understood the situation because of lockdown

*) UC said that may ** they will finish the JOB

* ) May **th , job was closed without prior notice - repeatedly raised may complaints but UC never called back , i am really frustrated with the service , even after spending ****rs i am still unable to sleep peacefully in this summer .


Conclusion :- Service engineer might have replaced the wrong Item ( since the same issue occured after * */* month ) . or they might have damaged the AC .
so with all this frustration with UC , i request my money back **** + *** rs .
