Urban Company — ac was destroyed after the technician had serviced and urbanclap not responding timely

Hi,

I have ordered AC servicing for Urban Company on 6th April at 415 am. They started with regular service and after a while one of the technician near the outdoor did something and we saw a lot of gas near the outdoor unit. And when asked the service person said it's just air to remove any bubbles in the unit like in the copper pipes and it's a regular exercise. The ac seemed to work fine and service guy was asking for 5 star rating which I gave later in the day when we were using the ac it was not cooling at all and I called one technician from my apartment to check and he told all the gas has been removed looking at the yellow marks on our outdoor unit. Since then I have been consistently calling the urban company and they are reluctant enough not to answer and to be noted this service was under warranty and I am paid premier customer o[censored]rban company
