Appalling Customer service from Cell c customer care

This is the worst thing i have ever had to go through. I called in to blacklist my lost phone twice and spoke to a Nosipho who asked me to call back because her system froze and she is unable to blacklist my phone. I asked how do I call you back yet your the one with a system problem. I am using my neighbors phone to make this call as i am without a handset. And still Nozipho could not even transfer me to another colleague to assist. I stayed calm and hang up as Nozipho could not do anything to help. I called back and Spoke to Mamusa who took me through the process, Took my IMEI number etc etc and suspended my sim card. She advised i would receive my ITC number within a few minutes. And my question to her was how would I receive this as i don't have a phone. Its a miracle she asked for an alternative contact. I gave a friends contact number. Morning came , I still had note received my ITC number. i called and got through to a gentleman who then told me there was no record of my 2 calls from the previous night. The gentle had an issue with blacklisting my phone due to an error ,Supposedly something to do with me using dual sims and that i must call vodacom to try blacklist as they are struggling to on their end. When did a system glitch become a problem on my end. I paid my contract every month without fail and my insurance without fail and even added a service that has not benefited me even one bit yet when its my turn to be assisted hell breaks loose. Its is completely unacceptable that your agents don't even sound eager to help on the line and all they care about is that they are only an inbound contact center. They cant even transfer calls between each other or a manager. I went to the store in clear water the lady could not assist either coz somehow they cant do anything as i have logged the call with customer care. I paid for sim insurance but apparently i cant get a free sim swap because insurance claim has not been processed and that is of course due to the lack of service on your end. Getting me on contract is immediate but servicing my need as a client takes days. As i type this an agent placed me on hold and has not come back and its been 55minutes. She was going to get me a manager. Someone by the name of Alan. I am still on the line by the way waiting like a fool for someone who might not even come back. I am truly disappointed. Cell c employees don't care about their customers .
