Electrolux Air Conditioner — Very poor after sales service

I purchased 3 of your acs from Vijay Sales on 5th May 2015 at Ahmedabad. model S18P33WC. I had to make so many calls to get the fitting done. After this the ACs were making noise, so I had to ask for a technician to come again. He came and confirmed that one of the ACs was not fitted properly, so he would see to it that it would be rectified. But he hasn't followed up or done anything about it, I called your call centre and my problem is being treated as a new complaint!! Why is your work so unprofessional. After each visit you have a feed-back call which is a total sham. The girl asks questions in a way that forces you to reply that everything was done well. I don't understand why you even have such a feed-back system which does not give you proper information. I have bought AC but unable to use it at the height of Ahmedabad summer at 45 degrees centigrade!! What kind of service is this?
