Can't get through to Call Centre to get ITC number

My phone was ****** yesterday. I tried calling the call centre and was told that the call centre was closed!! Eventually I went to MTN Canal Walk, where the consultant was very helpful - NOT!! He completed the blacklist form and then my sim card, after I enquired whether the sim could still be used. Once we were done, he told me that I would receive a reference number today. It is after 3pm, I have already received my case number from the SAPS, yet I have received nothing from MTN. I am unable to claim as I don't have the ITC number. The fact that MTN's call centre is closed, what am I supposed to do now. I can't get hold of any of their stores, which means I need to get in my car and drive to a store and then stand in a queue for an hour to see a consultant. I am sorry but this is unacceptable. I am already stressed from the mugging and now I have this to contend with. So not on MTN!!!
