Beware of Standard Bank whilst travelling overseas

I am a 72 year old pensioner, with Standard Bank for over 40 years, even worked there in the insurance department once! I am in the UK for an extended period, I send them my cell number in the UK but they told me they don't send OTP's for internet banking to international cell number but they can send it to my e mail address, this was not done. I then phoned twice and after waiting for over 1 hour I got through to Zunaid, did security checks, told him what I wanted, he asked me to hold, then we got cut off. Tried again, did security checks spoke to Gamo, same thing happened! Cost me R2500 in phone calls, no one bothered to follow up, they have my UK cell number! I have sent 7 e mails to try and correct this problem, still no reply! I need to pay providers in SA for some accounts! BEWARE OF TRAVELLING OVERSEAS USING STANDARD BANK, THEY ARE INEFFECTIVE, UNHELPFUL AND DON'T CARE! I am in the position now of telling my SA providers about the fact that I cannot pay them until this is sorted out! Clearly Standard Bank are useless!!!!
