Standard bank lost my money

I called Standard bank call center and ask how can I make payment to my credit card and the consultant advised me that I can do it from my app, I took his advice and make an EFT using card number as reference but now everyone is telling me that the money went missing, how can my money go missing if I transfered it to Standard bank and use my credit card number as reference and I was told by them that I can do so, R3500 down to the drain in the hands of Standard bank so why should I trust this bank if money can get lost that easily, I'm so disappointed because I always tell people how happy I m with Standard, when people share bad experiences with Standard bank I always think that it's a lie but ths time I believe everything said abt Standard bank.
