Dream11 Fantasy — dream11 fantasy dream 11 august 15 offer

Sir I have added 70 rupees today as August 15th I got message saying if I add 70 I will get 70 cash back but till now I didn't receive yet. Cash added at 10.49 pm so please resolve my issue. I am getting message stating if I add money I will get double or cash back but till now it's not happened so I need answer from you it's very serious dream 11 app looks a bit fraud thing. If I didn't get my cash back 70 rupees to my account then I am not going to play again.
my email id is [protected]@gmail.com
If you don't give me cash back then I won't use these accounts of mine and Uninstall this ###### app.
