Samsung Home Theatre — Speaker of home theatre sound is cracking

Complaint was lodged with Samsung in GK II who directed me to service centre.I spoke to them on three occasions.Each time I was told that someone would get in touch with me.The process started over two weeks ago but I have yet to receive any response.

I called this afternoon(21st Oct) and was promised someone would call me within two hours but its been 4 hours and I have yet to receive a call.Very very frustrating.

My complaint number is BP.No:[protected]
