Serious security issues SIM card not rica'd (mtn) by staff memeber

My whole life has been standing still due to negligent staff member, I went to buy an Mtn SIM card to do a SIM swop and keep my number. According to my receipt dated 22.04.24, my new card was rica'd instore. Status on receipt says SUCCESSFUL, It's been a week since I have been waiting for my SIMs.process to take place. Unfortunately after many attempts to mtn the status says confirms my card is rica'd bared. It is a whole week later I have done everything possible to do it thought the app, but now I have to go back to the store and buy another one. This has caused delayed communication and protection on my number. Ackerman's flora store, date 22 April 2024, how deceiving that Ackerman's paper work states it's done and successful. When it is not, and I am beyond upset and frustrated as I gave attempted all other avenues to avoid going back to the store. What must I do, buy a new card, drive extra petrol out, use if my time again because of staff members which I won't mention just don't take customers serious.!! I needed this done asap on 22 April. It's disgusting how they treat customers. Knowing that all our information is on our mobile numbers , there could be serious issues. Which in this case mine is.
