Berkowits Clinic — Not responding properly,not booking slot,rude behavior

I paid for full body laser for my daughter. The initial sittings were good and satisfactory. Lately, I have been having troubling getting my appointment fixed. The reason that they kept on giving was that the slots were fully booked but actually the equipment used by them was faulty. Since we got to know about this we were able to get our appointment at another branch. Now once again the same thing has been happening. The representatives at the branch we paid (GK) are rude and telling us to take the appointment but they would use different equipment than was stipulated. They haven't been helpful in making arrangements otherwise and delaying this for days. This is not the kind of service I paid for or the service I expected from a company with reputable name.
