Can't redeem my money market voucher and I'm being given serious run arounds it's sickening at this point

After all that drama with ShopRite money market is still havent been able to redeem my voucher, I have been emailing them and I also emailed everything they are asking from me. Today suddenly they tell me now my email address is that of a third party and they can't assist me based on that. Like why is ShopRite money market treating it's clients like that. Is this a new **** because it can't be. ShopRite I need my money please you have played withe its enough now😭
