Called first thing this morning and got through without much wait. The CM was very helpful and escalated my case to an "escalation CM". She was able to surmise with their help that the third refund was flagged or rejected during the processing (this was their theory not an actual indicator in the system). They said the third refund will be the exact same amount as the first two ~$3.36 per day remaining and will arrive by paper check.
Helpful information to have when you call: date you received the personalized cancelation email, date you received a cancellation confirmation, date of any refunds already received, and the contract holder for the annual pass (in my case all were assigned to me).
