Extremely rude customer service

I'd like to share my horrible experience that i had when i went to the BMG Head Office branch (0178) in JHB. I went into customer service for the 2nd time today due to my item that was i was looking for being scares so i was told to come back today. So when i arrived there today i was sitting waiting for help and as soon as the previous customer left i stood up and went to the counter and i was told no. I then stood there in shock watching the consultant by the name of Mandla that was meant to be helping me asking people that came before and after me if they had been helped. Once he was done he then knodded i then assumed he was ready to help me, i showed him the peice of item i was looking for and told him i was told to return for it today and showed him the gentleman that was helping me yesterday Timothy. He then said so what u doing here go back outside and wait for him there luckily Timothy had just got done with his customer so i could go through to him. Mandla was extremely aggressive and unprofessional and my heart was in peices when i left the place because of him and i feel someone like that should not be dealing with customers.
