I have recently bought by Ridaex 50" 4K Android smart tv from GOTMATTER website. Since the beginning the way of response I have got is very good. I have called them before I make a purchase to get the details of the tv which I am buying. They explained everything about the tv and features very well. Later, after placing the order they gave me a confirmation call regarding the order.
I called them a couple of times to get the tracking details and they were very best at support. They tried all possible way to get may delivery in priority with their courier partner fedex.
Unlike flipkart and amazon, customer support people need to care customers. That is what I got from gotmatter.
After receiving the order, usually all the other companies take about 4-5 days for sending the installation person. But my tv installation was done the same day of delivery where I would like to give 5 stars for this.
From now, gotmatter will be under my trusted sites list.
