10 day ARC extension?

Several coworkers’ contract expire June 30, and one is planning on leaving the country on 3 July. However, they won’t receive their final pay by direct deposit until Friday, 2 July. I’ve heard that a 10 day extension can be had for free, but the local Immigration Office in Tainan just told a Chinese coworker that it costs NT$1000. Also, there’s a fear among a couple of coworkers that they won’t be able to access/withdraw their money at the bank counter on an expired ARC.
Please clarify.

Never mind. They are now getting their direct deposit on the 30th.
