Pathetic after-sale service. These people do not know how to talk to customers. We had the misfortune of talking to their service personnel Ramya and she doesn't have even basic courtesy. It is an oxymoron to call it "Customer service".
The units they sell keep on conking off. They come and replace every part of the device, charge a huge sum and then within two months it is back to square one.
Do not buy anything from them!
