How does account crediting work exactly? Let's say I use the 500 minute plan, and only use 300 minutes that month. Does 200 minutes roll over to the next month or does Ting just pay me/credit me for the 200 minutes I didn't use?
Also, let's say I have the 500 minute plan and use 510 minutes one month. What happens to those 490 minutes I didn't use?
If someone could give an example that would greatly help. Thanks!
