Pathetic service Standard Bank

I recently moved overseas and forgot to change my OTP pin from going to my phone to going to my email adress When I emailed them, they said I must call. When I called they said I must email. I inbox you on Facebook on Monday and asked what to do and they said I must email some documentation. I sent it on Thuesday but no feedback!! Really it cost me alot of money to make a international call and nobody knows the procedure. I even cant log into my internetbanking now because it asked me my OTP and I have to make payments. Standard Bank I am fedup. And dont give me a stupid answer that you will give attention to it because that is what they keep telling me. Its been four days since I sent the documents. Start doing what you are paid for!!!!
