very disappointed

this is my second complaint on the same issue and its still not resolved i did say you cant call me on my cellphone as it is currently not working. i bought groceries on the 14th of december and the money went through but for some reason on the 27th of december i was charged again and the transcation i made on the 14th doesnt appear on my statement whch i dont even understand. this has caused such an inconvenience because my account is in arrears and i wont make any payment until i get an explanation and i also havent paid my credit card because of this and some of my accounts now im going to have a bad credit because of this. whats wrong with Standard bank and im seeing a lot of complains about them on social media and this is sad because i have all my products with and trusted them. please call me on ***
