Bad Customer Service

I was disgusted by the service provided today by Lennolene and Mantadi from MTN Woodmead... I have been a faithful customer since 2009 and I have three contracts currently active. I approached Lennolene and asked for a sit whilst we look at my accounts. She said she could only assist me whilst standing. After watching her 'trying ' to login' (for two minutes) I sat next to her without her permission. I then queried one of the cellphone numbers . She was playing with the browsers. I asked her if she understood the system; and she responded by saying i should leave and call 808 if i have a problem. I told her to behave, so that's when she became nice to me . Just before i left (5 minutes later), Mantadi called Lennolene and spoke about a client whom Mantadi had just served. Mantadi was mocking the client in front of customers saying that she is not obliged to speak all the 9 languages in Johannesburg. I told her that I was uncomfortable with her behavior and the words she chose because I am a foreigner. I would like to ask MTN to train their Woodmead representatives on how to treat customers and I would like an apology for the POOR service i received today.
