Aramex Courier — Not delivering the parcel, unnecessary delaying and rude response

Address:

Bangalore, Karnataka

I bought a smart phone online on 23 rd Sept from TRADUS. It was shipped on the same day from BANGALORE, Banashankari area thriugh ARAMEX COURIER. Even after a week's time, they haven't delivered it to me in whitefield area BANGALORE.
Daily have been calling courier office. They have been very rude and arrogant and say that they are intimating the concerned people...and can't do anything more and disconnecting the call immediately. Please help me, how to deal with them. Even TRDUS is not helping me out. My appeal to public is never go for ARAMEX courier and TRADUS.
