I called customer care on the 29/03/2015 to blacklist my phone but they said they couldn't as the hav a system problem n the agent said I must go to the store but I could as I was ****** and my I.d was also ******. I then spoke to a team leader called Shaun he then escalated a case for me n said I'll get feed back within 48 hours. I then called on the 31/03 to follow up but i was told that the was no case.I spoke to a team leader called Lauren m she said she needs 5minutes to check what happened n she will call me back but she didn't. I then called again on the 01/04 n i spoke to a team leader called Justin n he told me that there was a case escalated on the 31/03 n he will urge the case n i will be contacted with the itc ref number b4 the end of the day but no 1 contacted me. I called again on the 02/04 n spoke to n agent called nonkululeko i requested to speak to a team leader but she said that all team leaders r in a meeting n no 1 is available even the mananger refused to take the call.
