Overnite Express — delay in service

Address:

Mumbai City, Maharashtra

The ref no. is [protected]. I have not yet recieved my envelope which was couriered at 9th april 2015 from Nagpur. At the time of courier he committed that he will receive the envelope on next day evening i.e on 10th April 2015. But today is 13th april 2015. After enquiry I know that my envelope is in Powai plaza. As the person of your Powai office was saying that if this is urgent please come to Powai plaza and collect it. Is this your service? and why I have paid 100 Rs to you. Your delivery service is just like bullokcart so why you write express there. And I am going to complaint regarding that no one from your site was taking my complaint and not giving me proper answer. Sir if you can't provide your service please tell us at the time of courier. Don't miss guide us and don, t waste our time. I have never seen the bad service like this. Please give me my envelope as soon as possible. and take some immediate action on my complaint.
