Boat — Boat stone 1500 speaker sound problem

Address:

Palace colony 18/3 DISTT. MANDI H.P.

I send my my boat stone 1500 speaker to the service centre so they can replace my speaker or even maybe fix the problem but they only make it worse and send me back the same speaker and the problem becomes worse Base and sound are boath distorting i want refund or a new speaker its been only 2 months and the speaker causing problems i thought buying an indian product is good but now i regret my decision and now i know why people don't like to buy indian products because they are so cheap in quality and they dont even give us a proper service.
