PTron — Not attending to my complaint at all for nine months now

I purchased the ptron bass buds pro in February
I got a defective piece as the left earbud was not working
I have been writing mails to them to help me out and they have not given any response that is helpful I even returned my defective piece to their head quarters in Hydrabad and have not returned nor replaced my item
It is so damn difficult to contact them as there is no one picking up the calls there probably the worst company i have ever come across and can bet upon that i ever will i just have no words to explain my frustration for this company i hate this company so much that i would rather die than to make a purchase from this company ever again
