Swiggy — rash behaviour of delivery boy

The delivery boy used very bad language. And he even took extra money and got an excuse thatvhe doesn't have change which can't happen with a delivery boy. And also he used a very bad language when giving the order. We really want to slap him there but we can't do that because it was our college premises. Please look after this issue... We are going mad about this! He is just so annoying!! The language he used is really really bad.. And his attitude is even more worse!!
