Depending on what she texts back ("yes, it did. I'll get it to you tonight, sorry." gives her a chance to save face, possibly, if she just forgot 
) I would make sure to state "DCK cannot come back without payment".
No pay no stay. 
this is what I would do too. might even throw in a "since its already late" mention in there too.
Are you paid the first of the month? If so I'd post a reminder that if/when the 1st falls on a weekend or holiday that payment is required on the last scheduled day of care. I hate to say it but in a case like New Years when my kids were in preschool I'd often forget about making payment before the break and would just pay it on the 2nd or 3rd when we went back - but that meant thinking about it back on the 21st, 22nd, etc. and I just wasn't thinking that far ahead! Now, if this parent was just in on Friday then there is really no excuse!!
