Is it possible to find out how long my Prepaid account was suspended?

I have a prepaid plan and usually receive text message reminders from T-mobile a few days before payment is due at the end of the month around the 26th or 27th.  I didn’t receive any reminders this month, so I was surprised to find out that my account was suspended.  In my timezone it is still Sept. 25 at 9:30 pm.  When I tried to send a text message at 9 pm, I got a message that it failed and that monthly payment is due. I immediately refilled my account, but I would like to know how long my service had been suspended and if I missed any calls or messages while it was suspended.
