Bikanervala / Bikano — Stones in sweet box

Address:

RDC Ghaziabad Rajanagat

Hello,
I live in Germany, Nurenberg. On Sunday morning, I visited Bikanervala for buying some sweets for my office before returning to Germany.
I bought 1 KG sweet box and 3KG of the same kind in different 250gm boxes. Today I joined office back and offered the sweets to my colleaues.

Unfortunately, there are so many black stones in sweets that made the whole impression about the quality of Indian sweets staled.
I am attaching one of the photograph. Dont know, if such good restaturent is failed to maintain the quality, what is the meaning of paying hefty amount and bearing the insult for bad sweets?

I dont know even fully return can return the prestige of my gift.

I am attaching the photo, the black stone is near to the yellow slip right.
