Terrible service, extremely disappointed

I contacted Cell c customer care on the 16 March to report my cell phone ****** and have it blacklisted.<br> I was told initially that an sms will be sent to me with a ref. no. which I did receive. The call centre then told me that the case will be \escalated"as I have a prepaid line and I will be contacted in 24 hours. After no call back during the 24 hour period I contacted the call centre again on the 17 March and was rudely told that this process takes 48 hours not 24"
