Electrolux — Not getting any solutions even after repetitive complain

Address:

Mumbai City, Maharashtra

I observed proper cooling was not happening in my refregirator, immediately I intimated the electrolux customer care regarding the same complain no ETNA[protected] (on 25-APR-2014 Friday). The service provider came on Saturday 8:00 PM and told me there is some problem with the coolant and need to flush the Gas and refil the same.
This was mutually agreed and on Thursday (01-MAY-2014) the gas was refilled and informed that the problem will be resolved . For this he has taken 450/- (Service Charge) and 1500 (Gas Refill)

The same Problem was observed on Sunday (04-May-2014) i.e again the colling problem. Monday morning again I complained vide complain no ETNA[protected] and the service provider came today afternoon.
Now he is saying that there is no gas. This is quite ridiculous.

Till now I am following up to get this resolved but there is no response.
