FNB Connect- I dont have the nerves to put up!

I am trying to blacklist my hand set. I logged a call on the 23 May to have my hand set blocked, its been 6 days and none of the call center agents can give me any feedback as to whether the black listing was done or not. I have been put on hold for over 22min when I called the call center, and there after spoke to multiple agents who have no idea what is the status of the black listing of the handset. Each agent has different understanding of the process....one said it takes 2-5 working days to be done and another says it takes 24-48 hours....at the end I am still not sure if the black listing was done or will be done. The attitude of some of the agents is really shocking, as if FNB connect is the best thing since sliced bread. The handset has very sensitive information like my FNB App, email which should have been blocked already, but due to *********** staff at FNB connect and theres nothing I can do but rely on them , as it cannot be done in an individuals capacity. Not forgetting the numerous reference numbers! for the same black listing request. Its truly sad, the level of service FNB connect offers compared to the banking division, so much so that I am embarrassed to be banking at FNB.
