Disgusting behavior by RFO staff!

Wow. I've never, ever experienced worse customer service than I did today at RFO store in bellville. We were standing in line to pay and there was a bit of commotion because the customer before us was being treaded badly and was asking for better service. Four customer service agents were dealing with this man very rudely. The rest of us standing I'm line asked if we could get served whilst they handled the issue before us. We got dismissed very rudely and told to go pay upstairs. We obliged but during out walk up the stairs having a conversation the till operator upstairs starts shooting at us, telling us we are making noise they have customers here. And we asked "what do you mean, we are customers too" . The guy who was asking for assistance comes to talk to the manager -Lynn , who immediately dismisses him without even attempting to hear why he was disgruntled. We were very dissapointed and continued to have the conversation of customer service and the gustomer is always right. The teller from downstairs shouts at us calling us drama queens and says we are disgusting. The manager steps in and threatens to kick us out because she doesn't need our money. Not once did I hear anyone asking what the issue is and how they can help. Is there no training of staff ? The man working a till said we can complain at TFG but they will tell us that RFO doesn't go by the rules of customer is always right. The entire staff is rude and uncultured. Something needs to be done. I was personally insulted and called disgusting
