VLCC — Service denied.

I was trying to contact Vlcc Secotr 41 noida branch for my laser treatment appointment. But I was not getting any revert from them (as the staff who was looking into my bookings resigned ). So I called customer care and asked them to arrange . I got a call about my appointment confirmation on 05-02-23 . My booking was confirmed for 11-02-23 . However when I reached there I was informed that they did not have my booking and was denied service. I showed them the call records saying if I have received a call from the centre’s office no. I must have received appointment. However they kept denying saying they have no idea who called . Miss Arpita from Secotr 41 centre sis not help me about it .
