The communication by the Swimmattix Office is extremely poor

The communication by the Swimmattix Office is extremely poor. My requests are often ignored and, most times, disregarded. With specific reference to my communication with Mr Justin Lawrence regarding payment. I was sent a reminder email of my overdue account of R329 (6 days overdue), to which I rep**** that I would settle in the coming week. He disregarded my email and forcefully told me that my child is removed from the schedule and will not be allowed to swim until I settle an amount of R650. I questioned the amount and referred to the R329 outstanding amount... Justin then ignored my email communication and disregarded my request to please phone me. Despite this, I paid the R329 immediately and forwarded the POP to Justin. He then rep**** to say that until I paid R650, my child would not be allowed to swim, and he explained that the amount (R650) included a late payment penalty. I rep**** that this was outrageous. 6 days overdue, and this is the penalty? Additionally, I have never missed a payment or been late before, nor have I caused any unpleasantness ever during the duration of service. Nevertheless, I requested to speak to a manager to no avail. To date, Justin has not rep**** to our request to send a 3 month's statement, nor to refer a manager to me, nor reinstate my child's lessons.
