APPALLING SERVICE!!

THIS HAS TO BE THE WORST NETWORK I'VE EVER DEALT WITH!! OVER THE WEEKEND MY PHONE WAS ****** SO I IMMEDIATELY CALLED MY TWO CELLPHONE PROVIDERS. ONE WAS CELL C. ALL I NEEDED THEM TO DO WAS BLACKLIST MY SIM CARD. SOUNDS EASY ENOUGH, RIGHT? WELL, NOT WITH CELL C. THEY FIRST WANT TO ASK SECURITY QUESTIONS WHICH I UNDERSTAND DUE TO THE POPI ACT BUT OMW WERE THEY HAVE THE MOST RIDICULOUS QUESTIONS I'VE EVER COME ACROSS. NEEDLESS TO SAY, I DIDN'T ANSWER ALL 5 CORRECTLY SO I GET TOLD THEY CANT HELP ME. TELKOM ON THE OTHER HAND ASKED ME GENUINE POPI QUESTIONS AND WALAAAA I PASSED. HOW ON EARTH CAN CELL C EXPECT ME TO REMEMBER WHAT EXACT DATE I BOUGHT AIRTIME? OR WHEN I USED EMERGENCY DATA??? ABSOLUTELY RIDICULOUS! GUYS, STAY AWAY FROM CELL C. THEY TAKE YOUR MONEY BUT CANT HELP WITH A SIMPLE THING LIKE BLOCKING YOUR SIM CARD. THANKFULLY, MY DEVICE WAS WITH TELKOM :) :) :)
