Poor service from Vodacom

My wife's cellphone was ****** on the 28th of April 2026. I contacted Vodacom to blacklist the phone and was told that I would receive an ITC number which I would require for insurance purposes , to date I have not received anything from Vodacom , I have sent numerous emails to Vodacom and even those are ignored. As a Vodacom customer with multiple lines on their network , this type of service is **********.
