I haven't dreamed of such bad secvice

My Samsung Home Theatre system Model HT -B3550/XA stopped playing dvd's and I took it for repairs in on the 14/03/2016. I had to follow up after two weeks not receiving any feedback from the care centre although they promised feedback in 5 working days. Only to be advised that a certain panel has to be replaced in the unit and that part is not available due to the model being discontinued. I requested that a damage report being issued as this panel could have been damaged by lightning and my personal insurance does cover lightning damage. I had to send an email to [Email Removed] on the 22/03/2016 and was told that the waiting period of also 5 working applies. I have tried to phone the care centre on *** and the main call centre on *** for numerous time the last 3 working days with no joy of somebody to assist. Please Help!!!
