Fedex — priority delivery missed

Address:

500047

One of the worst experience i have ever had with fed ex .
I shipped my visa documents to India from Canada on 12 Feb 2019 with estimated delivery date of 16 Feb 2019 by spending 82 dollars for priority delivery through fedex
from 16 till 18 the Indian customer care showed no concern or respect for my 65 years old mother, every time she called she was given blunt answers like it was with delivery boy and she would receive it in few hours but in vain every time.
Last time she heard them giggling saying this old lady has no other work, she is continuously bugging us and they threatened that the courier would be sent back as address was not clear (if this was a case then how the hell can it travel from Canada to India Secunderabad?)
My mother just wanted the address of the office in Secunderabad where the courier was there, to go personally and collect it, but they refused to share the address or location. Finally after lot of effort she called the fed ex office in SP road where they gave her the details and finally she has collected it from one of the branch offices.
my tracking number is[protected].
I am planning to file a complain in the consumer court against fed ex customer care India, with all the call logs and recordings in this regard as no one should suffer like me and my mother in future.
Please rely of Indian post office rather than these fraudulent companies..a bitter lesson for me as well..
