Telkom Upgrade Deactivated my Sim

I upgraded my contract recently. The new device arrived today, however to my utter irritation my sim card stopped working at about 11:00. I restarted the phone and still nothing. I now call their technical call centre on the 081180 number. After speaking to Audrey, she tells me the sim card will not be working for 24hours as the sim is processed for the upgrade. What *******, what service provider deactivates their clients sim to process an upgrade. Whats more, the consultant who processed my upgrade Tyrone, didnt inform my about this nor is this information mentioned on their website. I've been contracted with other service providers, non of which require deactivation of services for 24 hours to process an upgrade. I eventually wait on hold with Audrey who claims all managers and supervisors are busy on the phone. She eventually stops talking to me and puts the phone down in my ear. I call back , stay on hold for 10 mins to speak to a very pleasant and helpful Sizekele who informs me that my phone needs the new sim card to be activated. SHe stayed on the line and talked my through the whole process. Audrey, **** and told me to wait 24hrs for my old sim to work. What horrible agent Audrey is to lie to me and put the phone down in my ear. Thank you however to Sizekele, i appreciate the patience and helpfulness.
