Samsung rewards but no rewards

Seems like samsung has fooled all of its customers by promises us rewards via the samsung rewards app, a client for 3 years now and I've yet to receive an award. I have huge amounts of points accumulated but there is never any rewards available. Everything is always sold out, when i did get a chance to place an order for a s7 screen guard (nothing else was ever available) one month ago, it still hasnt arrive and now my phone has even fell and screen cracked which would have been prevented had they delivered this screen guard by now. The rewards app doesnt even have a estimated delivery date, it just says "exp delivery date not available". This kind of service is disgusting from samsung and rewards was one of the reason why i chose samsung, i will be definitely changing brands now as i have to pay for a screen that could have been saved if thw *********** samsung delivered my cover, i urge all customers who are thinking about samsung devices because of the rewards app, Please do not waste your time, choose a better more user friendly brand
