USELESS TYM BANK

my cousin transferred cash for me last night from her tyme bank account to mine using tyme bank cellphone banking and my cellphone number , she accidentally pressed one incorrect number and send the money to the incorrect number and that money i was meant to give it to my little sister to go to see my grandmother who is very sick in Mpumalanga urgently , as soon as she asked me if i recieved the sms she then realized that she sent to the incorrect number and we tried calling that number and the number doesn't exist i immediately called tyme bank i spoke to the ***** department cause it was late at night and the lady told me to call customer care during working , i called today i spoke to a lady by the name of Candice who told me that there is nothing they can do i need to wait for 7 days for the money to reverse itself which i find pathetic cause we urgently need that cash my grandmother is sick and my little sister needs to leave as soon as possible , so meaning that if the number that we sent to exists the the person could have had enough time to ***** the cash whats the point of having that app if the most important thing we cant do ourselves , big banks like FNB and ABSA if you make a mistake you can reverse it immediatly i regret the day that i decided to close my account with FNB and opened an account with tyme bank they dont know what they are doing
