Received the following message yesterday but I already paid. They are persistent. Also it takes time to reflect on their system like 2-3 business days. EWB Final Notice: Your account remains overdue. As today is our department’s cut-off, immediate payment via bank over-the-counter is required. Continued non-payment may lead to endorsement to a higher collections department, which may require full settlement, and possible field visitation. Immediate action is required. Will there be any visitation? Or is this just a scare tactic?
