Insured device failing to process the claim...

If you guys fail to blacklist my insured device who do you think will blacklist it? Since I lost my phone on the 21st of Feb until to date you guys cant replace my device? Your customer service is not *********** since they failed to help me multiple times and kept me on the calls verryyyy long. Cell c is a **** guys, I think i will start reversing all your debits from now on mxm...
