Haier India Deep Freezer — Air conditioner

I brought an air conditioner and after 2 days of installation ac is not cooling properly and a problem is there in outdoor unit due to leakage of gas .
Called customer care 3 times and after registering complaint no service technician is able to attend or solve my issue.
Every time i call customer care same thing they are saying and no technician they are sending.
Kindly resolve my issue at the earliest.
