Patanjali Ayurved — defective product

Dear sir,
I am to report you that recently i have purchased 1 litre of patanjali kachi ghani mustard oil from a large store at no.1 main market, bhubaneswar & noticed the following 3 nos. Of defects in the pruduct.
1. The cooking pot is filled with foams when the oil is poured from the bottle.
2. The oil is comparatively much black & thick.
3. The smell during cooking is somewhat unnatural and different.
Such smell generally comes from very old and unused mustard oil.
Of course the shopkeeper reluctantly exchanged it with another brand mustard oil.
My point is why anybody trusting on swami ramdev will use such sub standard oil paying comparatively high price for patanjali brand?
Is it not a blot on your credibility?
Pl. Verify the products of this batch properly & intimate me accordingly and
Take approprate measures to avoid recurrence of such irregularity in future.
Eagerly waiting for your reply at the earliest.
With thanks and best regards.
Yours faithfully,
B b samantray, sr. A. O. (Vigilance), odisha, bhubaneswar
