Unable to retrieve rewards - 4 weeks with NO assistance from Discovery

4 weeks I logged a query saying I am unable to retrieve rewards from the App. I have sent screenshots multiple times and then 4 weeks later, I am asked to send a screenshot again. Discovery, it is the EXACT same problem. No matter how many times you ask me to repeat myself, ask for a screenshot, ask me to describe the problem, the answer will stay the same. I am UNABLE to retrieve ANY rewards on your app. I have over 140 coins that I can buy rewards with, but I CANNOT because your app keeps giving me a error saying it cannot retrieve the information.

What must I do in order to fix this? Your app was working fine for all the time I have been with you, and now I cannot use it. It is not acceptable that it takes 4 weeks for you to resolve a issue which I PAY for. This is not right. You cannot after 4 weeks ask me to send a screenshot which I have done WEEKS before for you already.
