Game Mall of Africa - disgusting treatment

Went into Game Mall of Africa this past weekend with the aim to purchase a few items. Whilst browsing the office furniture section - i came across an office chair and I got the attention of a salesman who duly assisted me. I thanked him and continued shopping. Whilst shopping - I then came across an office desk that i wanted to purchase (i had no intention to purchase a desk when i walked into the store but i liked what i saw and wanted to purchase it). I grabbed the attention of the very same salesperson and informed him that i want to purchase the desk. Said salesman then had the audacity to tell me and my spouse that we should have, "opened our mouths one time and asked for all items!" He then walked away mumbling in a dialect that i did not comprehend. He eventually did return with the item and I thanked him. He point blank just gave me a stare and walked away - again mumbling. This is poor customer service. Treating a customer as if they are a burden is just wrong! I did not want to make a scene and nor did i want to confront him! Game Mall of Africa - your sales staff are just plain rude and condescending, You need to train your staff better. You will not find me purchasing any other items from this specific branch again.
