I got delivery of this product from Amazon as per schedule. I started calling IFB Call Center for installation & Demo. Every time, I get the answer that technician will contact me and will come and install on the same day. But it never happened. After, calling everyday for 3 days multiple times and getting the same response. I decided to return this product which was lying in my house as showpiece and thinking of future on how much difficult it is to get service from IFB. I will be selecting any LG or Samsung model now.
