Ecom Express — Wrongfully delivery rejected

My name is Advocate Ravi Choudhary and I am really frustrated from your field delivery team and calling issues the delivery team Mr Ramesh Patel called me this afternoon and was around 800 m away from my home and I was busy somewhere so I said I will call you back in 5 mins but my call couldn't be connected even after several attempts and late in the evening today they have cancelled my delivery and raised issue that I had refused to accept what a pathetic employees do you hire he didn't even called me back 2nd time and raised false issues according to his whims
