Sun Direct — fraud ads are given in website

They have gvn info about recharge amount starting from 50' 100' 200 etc. Nowhere it is mentioned that customer wont get the whole amount. I rechrged with 200 and got only 176, when called they informed me that rest is gst, this is nothing bt making fool of people. Or else they would have mentioned the value we actualy gets. If you recharge a mobile they normaly mention howmuch we will get. Earlier it was not there, just making trouble. Now monthly amount is 209 and they dont have facility to recharge of 20, again i have to do for 50.
