Secondary OTP removed from online banking without notice!

No effort or ability to fix problems, terrible client services. We moved to Canada a year ago and set up a secondary otp on our account just in case my SA phone number stopped working here. 6 months ago this secondary otp number was no longer showing online and as a result I am not able to do any banking anymore. I sent email after email to FNB and the only response I get is generic useless response with nobody able or willing to help. I have a bunch of Canadian dollars that I wanted to transfer to this account while the exchange rate is in my favour but after struggling for about 5 months for them to start fixing problems I have serious doubts. FNB if you're reading this, please start acting and fix my secondary otp so I can use my online banking again!!
