Poor service from premier banking chat suit

I got really poor service from one of the consultants at the digital department of the Premiere banking chat suit.

He/She was very condescending and insinuated I was lying about a transaction despite me providing proof that the the transaction did happen. She did not help me at all and would not listen to anything I was saying and would not even acknowledge the screenshots which served as proof that I was sending her. I’m extremely disappointed and would like any apology from her as well as help with my request.

I requested to rate her service and they just disconnected me. I am disgusted by the way I was treated by this person. I deserve an apology not only from her but Fnb as well. I would also like help with my query. There’s money missing from my account and I still haven’t been assisted.
