SIM swap details not explained

Yesterday I upgrade my cellphone contract. It was told that my old SIM will not work in the new phone and thus they would need to do a SIM swap. A 3rd party member did the cellphone upgrade for me and they told them that the SIM swap will render my current SIM unusable as soon as they done it and because of this we asked that it rather be activated the following morning around 8am. <br> <br> The following morning, my old SIM was still working and the new one not. Phoned Customer support, waited for 10minutes before someone answered only to be told that the SIM will only be active the Next morning sometime since it takes 24 Hours after the SIM is made active before it is can register on their network.<br> <br> Why this was not explained at the shop when the contract upgrade was done is beyond me. All of this could have been avoided if they simply told us of the 24h waiting period. Next time tell your clients this information! Get your act straight Vodacom!!!
