Bad service and Bad attitude

On Tuesday the 3 march I entered the MTN store at 9:05 AM to purchase a micro chip sim card, after 45 minutes of waiting I was told to bring a proof of address. so I asked Mpho why he was giving me a nasty look after I had shown him that we have been waiting for 45 minutes before being assisted. he then told me that that's how he looks at annoying customers. so I left the store to get my proof of address shocked at his answers came back and I was made to wait for another 60 minutes. finally when I lost it and told them about their bad service I was completely ignored. then another assisted came in she was very rude and told me that its not their fault I must blame the system. so after being told this then then suggested I go to the other Mtn as they didn't have the software that can transfer my information to the new sim. Your staff at this store has the worst customer service on earth. I was in the store from 9 until 11 just to get a sim card.
