VLCC — Promised for money refund but not done till now.

Address:

Salt lake sector 5, Kolkata

I joined VLCC by paying 60k for a beauty package later they suggested me for a sliming package of 20k which i agreed at that time. Just one day later i confirmed them back that i dont want that slimming package and after a long discussion they aggreged that they will refund the amount 20k by cash to me. this has happened to me on September 2019, when last time i discussed with them on 2020 june they said they need some time so i let them have, but now 2021 jan, every time i go to them or call they only say that they have no fund so, they can not refund to me as corona has effected them. And now they even dont pick my phone. kindly help me on this matter.
Concerned person - Swagata and Deboshre saha from that branch i had all these discussions with.
