Tata — Tata Pink Salt Adulteration

I recently started using tata salt pink. I found sand in the prepared food. To check, i dissolved a teaspoon of tata salt pink in a glass of water and found residues of tiny white and pink granules. This residue was tasteless and definitely sandy. Even the filtered salt water left fine sandy residue in pink color (Pic attached). I have been using tata products as long as i can remember and to find adulteration in their product has shaken my trust in the company to the core. I hope to receive explanation for this.
