MTN Service sucks in all Departments - dont ever use MTN !

I went to MTN Stoneridge on the 12 June to purchase a Sim Card as my phone was ******. On arrival at the store there was no one at the door to sanitize the customer nor take temperatures - thermometer just lay on the table. The lady at the counter (Sibahle ) was watching a movie on her cell phone. She had 2 phones in front of her. She didnt care at all about serving a customer but instead watched her phone as I spoke to her. I questioned her giving me a Sim Card that was not packaged or sealed. She said that all Contract Sim Cards are not sealed . I told her if it doesnt work I'll be back . She failed to give me a receipt as well. All the time watching her movie that was more important. Can you confirm that I should have received a Sim card that was not packaged or sealed. She took the R150 I paid her, who knows she probably pocketed it as there was no proof of the sale.I wanted to upgrade my cell phone but with that kind of service , I wouldnt endure the service I received. Very dissatisfied customer. I sent a complaint to the ***, received ref no: ***. No one has since contacted me to get this resolved. My complaint is still not resolved. Now to further add to this, I called your customer service to upgrade my phone.I spoke to Simon on Tuesday 15 June, requested the IPhone 12 mini in purple. He confirmed all was in order and told me that DSV will call me to arrange delivery. I called back on the 18 June only to find out my upgrade was cancelled due to the pricing being incorrect on the brochure. Instead of R549 the actual price is R690. I was told by Lebo that this was a Marketing error and he cant help me with the upgrade if the price is incorrect. It’s been a whole week waiting for someone to assist me . I have the brochure with the deal at that price. If MTN made an error with the price this should not be passed onto the customer. I was also promised on Monday the 14 June that my Monthly bundles that I pay for will be transferred to my Sim card that I received the day before.I was afraid I would lose this. Today I called only to be told this was changed by MTN and there was no bundle due at all. I mean what next. Being a loyal customer means nothing. I have paid for these monthly bundles. I have endured enough with my phone being ****** only to be pushed from pillar to post by MTN.
