DTDC Courier & Cargo — regarding an important document

Address:

560003

We had sent important document on 19th october which supposed to be delivered to vyalikaval bangalore and the document was sent from koramangala bangalore through dtdc. Dtdc took 5 days to deliver it to the company in vyalikaval that is with a limit in bangalore city not even out station.
I agree friday was holiday due to deepavali festival, sunday was holiday but saturday was working still they haven't delivered. When i asked our dtdc courier vendor he said he has dispatched that on thursday (19th october) itself when he took from us but i spoke to vyalikaval branch they were bluffing saying today (Means monday 23rd, oct) it will be delivered but it wasn't it was a serious lapse, they kept a courier for 5 days with them when it is really emergency and it was a company audit document which was supposed to reach within a day. And this is a worst service happened with us many times. You guys have to serious take action on this.
