DTDC Courier & Cargo — Package not delivered and customer care service is unavailable

I am Aniv Mazumdar, my package tracking id is D63669937 and it was supposed to be delivered on the last Friday, but till this day, not a single delivery person contacted me, the customer care phone number is also temporarily unavailable, and I have been waiting for last 3 days for my package, but you guys are giving completely false reason regarding your incompetence in your job of delivering the package, first reason was that I have requested for delivering that package on a different day, which is completely false as I had insisted on sending the package as soon as possible, and on the second day the reason given was receiver wasn't available, whereas I was never contacted to begin with!
