Unorganized, unprofessional and a bunch of liars

A lady named Debbie one of the apparent directors of empire growth promotions, contacted us for help as she was so late with organizing usb's for her client. She called telling us 10 times a a day with stories about her child etc to try emotionally blackmail us. We were able to still assist her with securing the item she required, then she was not able to arrange a courier in time once again unorganized. So I offered that if she is willing to pay me petrol I will kindly drop off her items at her client, this was a Friday around 4pm, I sat in terrible traffic but made her deadline. She agreed that they would pay me first thing Monday morning. It is now 5 days later, she now ignores my calls and messages. Very disappointed, go out my way to help this women only for her to turn on me, extremely unprofessional and a 2 faced liar.
