Standard Bank NON Existent Customer Service

Standard Bank must be one of the WORST banks out there. I have tweeted on numerous occasions and not a single soul has bothered to contact me. I am overseas, my credit and debit cards are both activated for overseas use. I keep getting SMS' to reply Y or N confirming or declining whether I used my card or my card will be suspended. I CANNOT SMS! I have emailed Prestige Card but again no one bothered to assist. I cannot hold on indefinitely for someone to answer my call. Standard Bank your Customer Service is NON-EXISTANT!! I AM DISSAPPOINTED!!!! I have banked with you for over 40 years. It's time to change
