Panasonic — Air conditioner/no proper service nothing

Address: 600024

Respected sir/madam,
Our air conditioner is not working properly. If we call to mechanic no proper response. Nearly they visited my home 4 to 5 times just opening the box and cleaning this is only process they were doing. The mechanic came to my home to remove the ac and he going to take for service he did't bring a secure driver. See your service people still now he did't came to my home.

Regards
Jayakumar
