HTC should make enough spare parts before making or manufacturing the products. Your service center cant return back a phone after 1 month and now they say the entire mother board needs to be changed! 1 month back they gave me a budget of 4.5 k and now 9 K with a waiting period of another 20 days. Just because the part is not available with them.
Great going HTC!!
Keep up your efforts in fooling people around.
