No way to get through to Vodacom Corporate

I need to blacklist a Vodacom corporate cellphone. The phone in question was damaged and i need to blacklist in order to lodge an insurance claim. I need to blacklist the device with Vodacom in order to file a SAPS report.<br> <br> I have been trying for a week to get through to Vodacom Corporate to perform this simple task of blacklisting, but i am constantly transferred to the general inquiries call centre who try to transfer me to Corporate and then the call cuts after being on hold for over 30 minutes per call.<br> <br> This task of blacklisting is holding up the entire insurance claim process and i urgently need this to be resolved.<br> <br> Vodacom Corporate please sort out your customer contact channels as your company is extremely efficient at signing new customers on, but appalling at resolving existing customer queries and requests.
