Professionalism/lack there of OR Xenophobia

We notified Swimmattix in time that we will be dropping out [emails shared with Swimmattix and Accountability] We didnt do the lessons for an entire month after we gave "notice" We continued getting "absentee" messages for that month entire We tried explaining, and sent screenshots of the absent message that included the "termination" message; but we keep getting final notice emails. We tried explaining to Accountability/Swimmattix debt collector, they also decided to not accept our explanation, and continue to issue more warning emails that we need to pay [for what, when we notified them in time??] This clearly is not about payment, our team is asking, is it lack of professionalism, or is it xenophobia
