My particular branch denied my request for the additional business bonus due to the following wording on the newer coupons: "This bonus mile offer is not available to customers with an existing Chase checking account. Limit one business checking account-related premium per customer per calendar year."
But the two statements combined do leave the issue a little murky, or maybe a lot murky. If the limit is simply ONE account, regardless of what type, then why the need for that additional clarification of "one business..per calendar year."
It's these poorly worded T&C's that can make things such a hassle.
Good luck on your particular branch's interpretation. I'll have to try another one I guess...
