Patanjali Ayurved — Bad quality product

Address:	New Delhi, Delhi
Website:	patanjali

Amla murabba brought from a patanjali divya store in west patel nagar delhi was of good quality. On opening the jar i found amla turned completely black.
I went to the shop to change it but the shopkeeper was not changing it.
I also mailed to an emailid given at the patanjali site. But the id was not authentic. I called customer care no but none was available.
Kindly look into the matter.
