Ecom Express — Service of delivery agent and his boss

Your service agent is such a rediculous person when I gave him 30 rs in coins of 2 he refused to take and uses abusive language... He threatend me and called his boss I guess his boss name was ayush he told me to return parcel and returning my money stating that he will not take 30rs in coins and I have to return parcel and theaten me that by saying he will see how Can not I return the parcel...and his boss said HDFC bank does not accepts coins so he will not take. And agent uses wrong tone..this is not the first time when ecom delivery agent has done this ..this has been done on regular basis but today he was bad and yourr agents speak as if they own this company... rediculous and this is last time I am leaving this with only complain..next time I will fiel FIR against this company and obviously against your agents.
