Bank Mobile Vibe / bank not releasing deposit

I rented a rental car from Hertz from Dec 31, 2018 and placed a $200 hold/deposit on the card. The car was returned on Jan 2, 2019. As of Jan 4, the funds have not been returned. Hertz released the funds on January 2, 2019 but Bankmobile said that they would not release the funds until Jan 7, 2019. The first time that I called Bankmobile, they verified my information, asked me what the issue was, and then returned to the phone and acted like they couldn't hear me.
