Terrible customer service

I came in just after 5pm was in a rush and the lady who was supposed to assist me was busy on a call for a few mins. I was in a rush so I asked someone who wasn’t busy Satish paribhoo he immediately made sure I wasn’t seen nor bothered by me at all and sounded extremely rude like some who had a very bad day and I was his dart board. He has things to do he said got up and walked off after saying just wait in a very nasty manner . If rude was a person he would be the meme. I just changed my breaks which I’m sure is fine now but over all that service staff has disappointed me for a 2nd time. You’d think for a brand like Mercedes their staff would be happy to help. But clearly that’s not the case.
