Nutrabay.com - Not getting a refund or replacement for a protein powder that looks adulterated fake

I ordered myprotein chocolate smooth *.*kg impact whey protein powder pack from Nutrabay.com. on **th Feb, ****.
It got delivered to me on **th Feb, ****.
I opened the packet for the first time on **th Feb, ****. Thereafter, i took a scoop, put it in my shaker with water and started shaking. I observed a lot of foam being generated which was not the case when i had consumed the same flavour from the same brand for a month. I then noticed small black/brown particles floating in the mixture and starting to settle down once i stopped mixing. Ignoring all if this, i took a sip and found the taste to be bitter.
That's when i knew there's sonething wring with the protein.

I then opened the packet again took out some protein powder in a vmwhite plate and i could see tiny black particles within the protein powder.

I contacted nutrabay.com and at the same time i contacted myprotein website as well.

Nutrabay.com is still sending back and forth mails to me but haven't done anything so far.

Myprotein simply said that since the product hasn't been ordered from their website, it isn't their responsibility so they did not authenticate the product.

I am stuck in between now with my time and money lost. I seek a full refund and an apology from Nutrabay.com for wasting my time and sending me a fake product.
