Khazana Jewellery — Cheated many people by the name of Monthly scheme and PAR closure

Scheme employee id: 48N612

I am part of Khazana monthly scheme and i payed for 7months, all of sudden they layed off the showroom asking us to submit the proofs to settle the amount what we payed.
At the start of the scheme the requested us to open the schemes and they offered few gift items.
Now, the situation is reverse though we have payed scheme amount of 28000, they are ready to pay only 26500 and they remaining amount they are charging for gift item.

Did we ask for the Gift at the time of scheme initiation ? how you will deduct the money from us.

And one more point, from these 7months we have payed scheme amount and where is the interest for that ?

Are we looking as fools to you?
