Continuous Correspondence leading to dead end with Cell C

I requested that Cell C confirm the blacklisting of my previous LG G3 phone that was ****** a MORE THAN A WEEK AGO. After going to Cape Gate Mall branch round 6 times to get this done, they said the sim swap was done but not the blacklisting. I received a call from Cell C this morning informing me that it still wasn't blacklisted. I was shocked and disappointed, as how long does it take to blacklist a phone? the consultant informed me that she would send me a form. here's the funny part... I'M STILL WAITING ONCE AGAIN! the form must have been sent via a messenger bird! The min this is done, I am moving over to another network, because the service is atrocious!
