Worst service ever

Well how do u start my story off. Well let me firstly tell you this that cell c is the worst service provider for phones. The last time I put a insurance claim it took 11 months for me to get my device. Now again I have put a claim threw Cell C Csurance and once again it's been 2 months and no feed back or no response from Cell c. I submitted this claim on the 17 July 2019 now we going on to 2 months and still no reply from Cell C. I as the client fail to understand how Cell C work like this and have no customer service and don't understand how things should be done when delivering customer service. Since I have submitted this claim on the 17July 2019 I haven't even received any feed back from Cell C absolutely zero communication from Cell c not even a sms or a email. Cell C is the worst service provider that anyone can ever go to. The amount of problems I have had since joining Cell C 4 years ago have been endless. Sometimes I wish I neve left MTN as they know what service delivery is. Anyway I now phone Cell C Csurance this morning almost after 7 weeks later and I get told that my claim had gone up to management and that it had been declined due to the fact that they say the sum card was not linked to the device. My question is am I insuring the device or am I insuring the Sim card.? This is an absolute JOKE AND CELL C IS MORE THAN A JOKE. I am very unhappy with the way you CELL C handle and deal with customer service. You people have NO CLUE AND NO IDEA ON HOW TO DELIVER GOOD CUSTOMER SERVICE. YOU CELL C ARE AN ABSOLUTE JOKE AND I NOW UNDERSTAND WHY CELL C IS IN DEBT...... PLEASE PEOPLE DON'T JOIN CELL C... MANY THANKS WARREN
