Class of 53 Driving School - Failure to deliver service after being paid !

Money for full 10 hours driving package was paid over in December 2020, for my daughter's lessons. We explained the need for her having a license before end of January 2021 as she just finished matric and needed to look for a job. End of January 2021, with 2 hours lessons still outstanding, she said we needed to pay for another additional 5 hours, thus now 7 hours outstanding. Last driving lesson, and last communication between the owner, the trainer and ourselves was on 23 January 2021. Despite numerous efforts from our side to make appointments with owner, our messages were read but unanswered. The owner refused communication with us as according to her, she could not get a booking on the e-Natis system for us. Suddenly, after 3 months of no communication from her side, she phoned late on a Wednesday morning to say my daughter has to be at a testing center to register and pay the next day. Due to work, my daughter was unable to make the appointment and asked to re-schedule. The owner did not communicate with us since January or confirmed the availability before making the booking. The owner did not re-schedule the appointment and once again, refuse to communicate with us. Up to today, they owe us 7 hours driving. Today we requested a full refund of the monies paid for the 7 hours, and the owner started threatening my daughter. Besides paying the full course amount as was requested, and the owner confirming receiving the moneys in her bank almost immediately, she now claims she wants proof of payment (which we have). there were also a lot of hidden costs, like paying R40.00 additional for every driving lesson, and the additional R250.00 for bookings.
