Stranded. Hopeless. Desperate

I find myself in an unusual situation regarding my online banking - traditionally my OTP is sent to my SA Cell Number - I however recently moved to Santiago and my SA cell number has been ******. Now I need to make payments from my bank - however without a OTP I cannot do anything. My personal banker has called me several times and put me through to the Online Banking department - which just rings endlessly and then the call ends. I have tried calling from here a few times also and the same process happens. This has been going on for over 2 weeks and I am now done.<br> <br> In the years I have been with FNB this is the worst service that I have received yet. I am sure that I am not the only person who has ever moved and needed their OTP changed to their email address? Why is this so complicated and where are the agents to assist? I am now done wasting hundreds of rands calling SA. I need this problem resolved before my credit rating gets destroyed due to FNB's lack of interest.<br> <br> I expect someone from online banking to call ME and sort this out.
