Appalling Service from MTN Killarney Mall

I have been a loyal client of MTN since 2001, using specifically their branch at Killarney Mall, Johannesburg. Having just recovered from COVID, however still recovering from the backlash of the virus, I took my son to the mall to acquire a new contract for him because his current phone has finally reached its "used to the max" stage and is completely broken. I have mentioned my COVID in this review to try and paint the picture of how urgent the phone actually was due to my son having to have to travel approximately 80kms a day to and from work and it is extremely vital that we get our hands on a cell phone immediately just in case he were to experience any emergencies on the road and due to the fact that hes a very new driver (6 months to be exact). So we get to Killarney mall, the MTN, go through the process, chose the phone (IPhone 12 Mini) the lady advised that they did not have stock of the phone and in 3 days they would deliver the phone to us. I opted to take this option. Today is day 3 and I call the store to find out if the phone is out on delivery only to find out that the actual processing time is not 3 days but in fact 5-7 days. Had I been given this piece of information on Sunday, I would not have accepted this as now my son has to still drive and I have to stress myself out not knowing if he is safe or not. I am appalled by the service of MTN, the lack of knowledge their staff has, the terrible service which I am experiencing. I asked for a leased or courtesy phone, they dont offer it. I asked to cancel my application in order for me to make another plan to get a cell phone earlier, apparently thats not possible. I would like to know what is it that MTN is going to do about this bull**** treatment I have been succumbed to?
