TopCashBack USA

I joined TopCashBack in Sep 2017 and has been a loyal member. Over the years, I have earned $262.52 and redeemed $115.15. I read in the news recently that merchants like *** and *** stopped partnerships with shopping portals during the COVID-19. Realizing I still have more than $110 available in my TopCashBack account for immediate redemption, I decided to use it to help my current financial situation. Surprisingly, my account stopped working even though it worked fine just a few days ago. My mobile app still shows my earnings, but I cannot redeem anything. Resetting the password resulted in an error as well. The "Customer Service" link redirected me to log in. After Googling, I found some posts saying that the symptom indicates that TopCashBack suspended the account. I cannot believe this happened, because I did nothing that could have violated the Terms & Services. Initially, I thought TopCashback might have some concerns with my recent friend referral. However, after checking with him, he confirmed that he hadn't even joined TopCashback yet. Other than that, my only interaction with TopCashback this year was a purchase on Yamibuy on March 28 as I participated in a $3 Extra Cash Back promotion TopCashback emailed me about. When I made that purchase, I carefully followed TopCashback's instructions: I cleared cookies and disabled AdBlock before making the purchase. I honestly don't understand how TopCashback could have suspended my account. In fact, even if I failed to follow the steps exactly, the cashback transaction simply wouldn't be tracked or declined by the merchant. I don't see how that could logically lead to account suspension. My friend suspects that TopCashback suspended some high balance account to avoid a "bank run" during the COVID-19 pandemic. I don't want to believe in conspiracy theories but cannot think of any other reason unless TopCashback made a mistake.
