I had some problem in my Ac ( showing F4 error) . I did a complaint on their toll free number and they told me that someone will come to check. When technical guy came, he told us that he dont have part. He then took a week to get that part replaced which was again defective and stopped working same day. I again did a complaint about same which these guys never cared about and they kept on saying that tehnical guy will come. Which finally visited after 15 days fight with croma. And that too happend when Ac was in warranty. A very shameful act for the brand like croma. Their services sucks.
