Sangeetha Mobiles — Warranty not claiming

I bought an headset just 15days back and currently its not working oneside. When i checked with showroom(Kamarajar salai-Madurai), the person is not a professional manner and simply telling that you pulled the wired so its not working. Then i asked thats fine, get the same response from iball then i will agree. Without any technical knowledge how those persons are answering directly to the customer very rood. Whether did he came and saw when i pulled? The wire looks same way from i bought. And the person is telling that sangeetha is the decision maker to take the warranty request or not. Is that true? Sangeetha is manufacturing those products then? I need proper justification from sangeetha higher level. Its just 300rs but thats not an matter. the person who responding is very very worst. Instead of buying it from sangeetha probably next time i will plan to buy it in rodeside. If i get the same answer from iball i feel okay. how sangeetha people is deciding that? Why they are not raising the request atleast? The true fact is they don't have the replacing headset in their showroom now. Also i said i dont want any exchange, take the headset and get the response only from iball. but they ignored. Please take this serious and response to the people properly.serial number of invoice - SI/MDU3/164.. Authrorised by-sivakumar(13045)
