Overnite Express — rude arrogant behaviour of staff

Today i went at overnite express to courior a box on that a man sitting there asked me address. I said just a minute mam as i was asking adress on phone call. On which she replied address b ni pta.in rude way. I asked mam kitne time me deliver ho jayega. Again in same way as it seems she was making points of at front of staff that time to lgta h phle aap address do. Fir bola 2 days. Indirectly she used vulgur language (Like bta tu). Other emplyee asked me leave my courior item there as they will call me later when server will be start working. I got agree but i didn't get any call from there till evening so i moved to shop and there that mam was absent so somehow i talked to that guy. He started to fight with me that why i didn't said to mam if her behavior was rude and language was wrong. I said him bcs she was not worth of talking. But that guy itself started a quarell with me on this as from starting he was in favor of that mam as it seems that is why i was silent.
I will never go again on that shop. We hv a business so we often courior, but i'll give very bad feedback to all over my circle of business. As i m already doing. Even rating of your services also bad so i got it that i was at wrong place where employess fight just bcs of no reason.
There were two mam one younger and one older to her. Younger one misbehaved extremely. And that male person also fought after complaining.
