Disappointed in the service provided

I made arrangements with Voilet for my daughter. I asked her if we could do payment arrangements as my daughter does not earn a lot of money. She agreed and she advise me as we go along we can take more lessons. My daughter faithfully paid them off making payments every week. She took the 5 lesson Option but when it came to her last 2 lessons it came across as there always an excuse why my daughter can't do her lessons, my daughter lessons was always sheduled around their schedule and it never accommodates my daughter My daughter works shift hour and she asked her instructor to give her lessons before or after work but he declines. The hours my daughter works does not have an effect on the traffic in fact there is no traffic the times my daughter works. I did communicate with Voilet regarding this issue and level of professionalism I'm very disappointed in the service we experienced
