Flipkart and Jeeves pvt ltd - AC repair service not done

I buyed Hitachi AC from Flipkart on April ****.It was *****rs .The installation was done by Jeeves (Flipkart installation unit) .
I extended the warranty of the product from jeeves end .That cost me ****rs . It was working Fine.
On *st the Copper pipe that transfer gas from indoor unit to outdoor Burst and my whole family felt threatened thankfully no one got hurt due to that pipe burst.
I contact Hitachi and they told this happened due to the FAULTY installation.
I contacted flipkart and flipkart was ready to refund the repair.
The technician from jeeves came on **th july and he repaired the unit but didn't provide the invoice as as per him on sunday they don't have invoice.
On Monday the very next day ac broke down again.
I contacted flipkart and technician came and he investigated and the PCB of outdoor unit was burnt .He took the PCB to jeeves and told the invoice will be send after complete repair .
Today its **st July **** and no update from Jeeves and flipkart .The ac was bought for some reason which is not met and my family suffered.
