Patanjali — Patanjali wheat flour

I have bought the patanjali wheat from nearest retailer shri blanket bihari store the quality of wheat flour is so worst there is lot of worm in the flour when i went to the retailer he refused to take it back or exchange he said that he can't do anything
Seriously they are charging a lot of money compare to market but they are not giving the quality they are making the public fool by packaging bad quality of flour.
