The Professional Couriers — Package not delivered: deliverd to wrong address

I had ordered for a few issues of a magazine our company was publishedin. The delivery was supposed to come from Mumbai and be delivered by 20th December. It is 2nd january 2016 and my package had not been delivered yet. I checked the tracking number provided by the courier and to my disbelief the message said it had been delivered on 23rd of December 2015 and also had been signed! where as I did not receive anything at my office. The more shocking part is that the delivery address is in Jubilee Hills and the package was delivered to someone in Madhapur. After repeated attempts at contacting the Madhapur Branch office, there was no help. The people were not helping and non responsive about the whole deal. I am still left with no answer as to where the package is and if I will ever receive it. Most horrible courier service ever.
