Poor service and undermined by Mtn staff at birch acres mall

Am so disappointed with a service we got from mtn birch acres mall in Tembisa

My mother wanted to replace her SIM card , Grace assisted her, she told us that their machine for rica is broken so they won't be able to assist , ok cool that I understand we asked can we go and buy and come back so that she can assist her for SIM swap because she won't be able to do it alone as she is a elderly person she refuse literally refused she told Mom that is self service she won't be able to assist her . When I ask her but she won't be able to do it atleast if you can assist she reply by saying no she won't be able to assist as that is self service!!!!!!!!

What is happening at Mtn , is Mtn hired the staff that refuse service to the customers ?? If she can't be assisted at Mtn where should she go or should we change network because of a rude ,not helpful staff from mtn birch acres who refuse to assist , she even asked ist contract or prepaid meaning the only people who deserve assistance is people who have contract not prepaid Am really disappointed not only for Mtn birch acres but Mtn as a whole , as grace working for Mtn she represents Mtn with a nasty attitude

Surely she wants contract clients for sales , not interested on the prepaid customer

Mtn can you please educate you employee to treat customers good especially those who work in locations like birch acres because they seem to neglect their duties
