I read these kind of post all the time too, honestly you should not feel bad about cutting her loose. You have sent her all the information and she still can’t follow the rules…. As one of my good friends said “you are making her problem become your problem”. These kind of situations will just drain you even more and be an aggravating moment every time you do business.
I would cut her off, the next day she was late with payment, you probably have other people standing in line to order and you are wasting your time on this person that doesn’t even take you seriously.
I would just sent he a message the day she was late with the payment and say you will not be able to proceed her order because of no payment….
Why should you be expected to run after her, she is a grown person. Sometimes being strict is better than being too nice. For your own good.
