Boat — I am complaining for unresponsive behaviour of support team towards customer

I've been purchasing boat products for many years in terms of various accessories. Recently i've purchased headphone (Boat - rockerz510) on 28th september. It was working well for few months but after march there was a charging issue (Charging light not blinking) which i am assuming that it might be due to the short circuit in internal wire.. After that i tried to contact various boat center across my location but wasn't succeeded with the pretext of not repairing this particular model (Rockerz 510). Then i tried to contact you via mail but again i didn't succeed as there was no response from your side... So, being your loyal customer if that kind of pathetic response (Which i was not expecting from your prestigious company) i will get from your end then it eventually tarnish your reviews and rapport... If you have an iota of oblogation towards customer then reply me asap before 28th sep (Warranty period last date).. If there won't be any response from aforesaid date then i'll assume that you were deliberately waiting for my warranty period to get over... Hope all the above thing will make sense to you...
