I have been a TollTag customer for 10+ years. When my license plate would change, new vehicle, debit card changed, etc., I would receive a ZipCash bill. NTTA realized I was a TollTag customer, would charge me the TollTag customer rate vs. the non-discounted rate. We'd go about our business. NTTA has since done away with that policy. Even as a TollTag customer, if you receive a ZipCash bill, you do not get your "customer discounted rate" but in fact are treated as if you weren't a customer. But wait! If you've never been a TollTag customer you can receive the discounted rate by setting up a new TollTag account. So customer for years > no discount, no apology. Never been a customer > discounted rate. Terrible organization but can't take my business elsewhere as they have a monopoly on all toll roads.
