COVID?!!

We were the position to settle our GAME Account last week. We did everything as the person on the other side of the phone told us to do. During the weekend GAME kept on sending us SMS's saying we must pay our instalment. So we called them last night to inform them AGAIN, that we did settle our account last week, and that we also want to DECREASE our limit on our account..... The lady on the phone told us that because of COVID, they can not DECREASE of even increase the credit limits on the GAME accounts?! Really? So now everything is because of COVID? How on earth is this possible? We have never missed a payment, now we just want to DECREASE our ACCOUNT and they tell you that because of COVID they cannot DECREASE it? This is ridiculous. Hereby I want to know why we cannot DECREASE our account, and the excuse of COVID is unbelievable and to be laughed about!!
