Disrespectful staff member

I attended Marshall’s at A6 Timberlane Avenue retreat on the 7th of December 2020 at about 15:50. I am a regular customer an I was insulted badly by one of the tellers named “celest” she had a terrible attitude she chased me from her lane to another lane an then I just shaked my head an then she went on talking an then she started swearing my **** infront of the other customers an I asked her is that how u speak to your customers an she repeated herself an said I can report her.
