VLCC — Refund request refused

Address:

Vlcc karama branch

I have made an appointment on 12/10/2021 at vlcc Karama branch and I have made a booking for a treatment. I have paid 1365 aed for that, but unfortunately I am not able to attend the session as I have leaving the country on 15/10/2021, so I requested to cancel that and request for a refund . But they people is saying that everything is written on the invoice and we will not refund, I have came there the same day and begged for the return, cuz am leaving.
But Vlcc people haven't any mercy towards customer, they focusing only money more than customers satisfaction.
Very bad service
Keeping someone money Un authentically without giving a service.
