NO IDEA HOW TO HELP ME? ITS TOO HARD!

My daughters phone was ****** 02/08/2022. I blocked the prepaid nr & sim. I have been waiting for the Black list number for the IMEI since then case *** (this case was closed without any notice given to me) . I call every day to be given the run around! On Monday 08/08/2022 after calling the 100th time *** was opened . The phone was purchased separately to the sim. These *********** so called customer care people are not capable of assisting. As this is too HARD / Technical for them!. I have since sim swapped the number & replaced the phone. HOWEVER SAPS will not give me a case number without the ITC Number for the IMEI. My insurance will not process my claim without the case number & itc reference. IM GOING AROUND IN CIRCLES WITH CELL C! ... I HAVE 4 CONTRACTS WITH CELL C . IM SURE VODACOM OR MTN WILL GIVE ME BETTER SERVICE!
