MTN WATERFRONT & their staff's BAD attitude

27 Feb I upgraded at MTN Waterfront. I called to confirm if the phone was there. Gerald was friendly on the phone; completing the paper work before I arrived. It was later hard to look past his arrogant attitude,I realised the telephone nature was just to make a bit of commission.I looked past it; I just wanted the phone.5 March,I returned to report that the phone is heating up.I approached Gerald who was NOT busy at the time (perhaps waiting for something) I told him the nec,he told me to sit asking if I have the box etc.I later got up telling him ill come back.(He was now counting money in front of a customer), NOT TALKING TO HER.He then asked when I upgraded (I told him this when I walked in).He then said it's out of the 7 days.He repeated this numerous times not looking up ONCE.I got annoyed & he started raising his voice saying his busy with a customer & I walked past everyone in the store,came right up to him not respecting the people in the Q.WHY DID HE ACKNOWLEDGE ME THEN,HE SHOULD HAVE SAID I'M BUSY.I've worked in retail, I know how to make a customer feel,THAT was not it.I always praised the MTN network,I no longer feel that way & I've been a customer for 12 years.
