OTP problem

I registered my account in Internet banking so that I maybe able to do transfers and payment. On the 07/03/2016 I tried to log in to add two more accounts and to do one Once Off Payment, I couldn't get OTP. On the 08/03/2016 I tried again with the same process and failed to get OTP again while waiting for more than two hours and all the time trying and trying. Then I decided to go myself to the Lambton branch for assistance, the gentleman by the name of Nelson Podike assisted me to do it again on their laptop, again we waited for no response from OTP side. Then he told me to go to teller and ask them to do transfer from their side, thee teller told he can't do it. Nelson then dialed the call centre where I spoke to Frank and who told that he needs to transfer to someone so that I can verify my details which I was also surprised because before you can be put thru to someone that's what we do first, then he hung up my call. I left the branch without any assistance. Today as I write this message I tried again (09/03/2016) to log in, still no response from OTP side. I can't go to bank and withdraw R18K and walk around with it. No, I don't need such a service, I'll have to close it
