Nike - Extremely unsatisfied by the product quality & having doubts about the authenticity of the company.

Sir,
It's been * to * months since I bought the two Nike t-shirts online from
Amazon of worth **** Rs & **** Rs respectively. The first t-shirt was a
plain black Nike t-shirt with a Nike tag on its left side & another one was
also plain black colour Nike t-shirt which was of spandix and bodyfit t-
shirt for pro athletes . Both the product were very impressive regardin
their looks & hardly I weired them about * to ** times occasionally. But
what I experienced or noticed after few months of purchase was
really ridiculous as well as unfaithfull . The first Nike tshirt tag started
diminishing and the day when it started diminishing after few days it got
completely diminished. And even though there were no casualty shown by
my side even I hardy washed it * to * times around the whole month. And
now the second t-shirt tag has also started fading , the cracks have started
emerging on its tag and I am fully sure that within few days of usage its
tag will completely get faded. Due to this iam not even able to wear them
as I have told my friend earlier that it was a genuine product which I bought
from Amazon and for now I don't want to be the one to whom people would
be laughing at or calling a lair.
Despite of all this *yrs ago I bought a Nike shorts from Nike showroom .
It's bee * yr since I purchased it though neither its tag got faded nor its
quality has changed.
So, regarding the concern problem I just want to know if the company has
decived me or the online shopping site(Amazon) has. And what about my
loss ,faith regarding Amazon which I thought to be a wise shopping site to
their customer.

I hope the concern authorities will take a serious and urgent action
regarding this serious problem so no other costumer have to face
any problem like this.

Thank you
