Unhappy customer 😑

I paid a deposit almost 2months back and I forgot about the due date,I mean there's supposed to be a reminder,now she tells me that I have lost my 50% and she continues to say that she has 1000 people, how was she supposed to remember me,mind you the people that recommended me to her they got a reminder to pay the balance a month before ,but with me she doesn't have the time,if only I could post the WhatsApp screenshot.This is not a way to treat your customers ,it means she chooses who to remind 🤔. I was supposed to take the trip on the 5th of December 2025,meaning my I was supposed to pay the balance on Wednesday last week, how was i supposed to remember that,she's the one running a business she needs to remind everyone customer, not chooses who to remind.I gues the priority is the money not the clients.
