The worst Customer experience ever!!!!

I was due for an upgrade, did it online as Vadocom call centre staff is not the most efficient in the world, and it was proven again this week, ordered my phone, got it.awesome.open box, wrong SIM Card. Called 082111, explained my situation, All i want is to please receive a NANO SIM, I was placed on hold, transferred to ***, (Upgrades), Sorry Sir we can t help you as the order was done online, Placed on Hold , Transferred (again) to 082 19 44 (repair center ***?), Call was Transferred again to ***, Sorry Sir cant help you, after the 5th person i lost all calmness that i had and i requested to speak to some one that can assist me, finally the one bright spark among(KILE) them helped me, placed an order for my new SIM, 2 days later SIM arrives.SIM SWAP TIME.WRONG, after phoning 082 111 choosing the option for SIM SWAP i get to the most arrogant Call Centre agents, all i wanted was to do a sim swap.NO sorry we dont do it over the phone...go to a Vodacom Shop. And phone was hung up. If this is the case then WHY DID YOU NOT SAY THIS WHEN I WANTED A NEW SIM, then i would have gone to a shop when i received the phone?If this is service ill rather close my account and move on
