Lazy and bad customer service (sabelo)

I have been to MTN ilanga Mall few times for a sim swap without being successful. Every time i get there i find Sabelo, the guy is very lazy, He look for excuses to send you home. Firstly he told me i need proof of address and ID, I produced iD and I told him i got a soft copy, I can print it and bring it, he said no, he want original. I came back few days with originals and he send me back because the system is very slow. He says i should cut my micro sim to nano sim. The guy is useless, he is only looking for sales and commission. he choosed the wrong industry. No will just go to the grove mall to do my sim swap or port my number to other network. The guy even refused to sell me a sim card. I'm so upset with mtn, and now i can't wait to terminate my contract once is expired. But i'm going to request a settlement amount for my contract. I can deal with lazy people at wrong fields. :(:(:( Regards Lucky Maeko ********** 078
