Dear, the problem was not the inflexibility of providing a test class, but the terrible service that was provided from the beginning. To begin with, the attendant did not ask how I was doing or what was the reason for contacting me, he just sent a photo with the times, when I asked about the possibility of scheduling a test class and if that was the standard of care, I was invited to look for a new studio.
The fact that your Marketing strategy is flawed or not, for me is indifferent, what is relevant is the customer experience, which maybe you are not aware of, but it starts online. Therefore, I am very sorry if during the 9 years, in addition to the inability to sell, the skill of receiving feedback for the service provided was not developed.
