VLCC - Misinformation and fraud

had no idea about laser related services untill I visited the vlcc salon for a normal face wax routine where in I was convinced to take permanent laser hair reduction service worth **k + GST which costed me around **k. I was told *-* session are sufficient for the face permanent hair reduction and you'll good to go, but today after ** days of my final/last session I see hair growing back in the same manner and thickness and when I shared my concern at the salon they say ma'am this was ment to happen as one has to take maintenance sessions too which is a must and will cost you another small amount!!! Now the thing is weren't they supposed to tell me this on a prior basis, a customer must be completely informed when he/she has zero knowledge about the service and I swear If I knew this would happen, then I really feel I shouldn't have spent my money in here on VLCC instead I should have consulted a proper dermatologist, atleast they would be genuine.
