FNB taking money from my acc without permission

On 28/9/2015 FNB took a large amount from my cheque account, as it is 30/9/2015 I would really like to have the money back into my account as I have obligations to attend to, FNB had no permission to do so, and now I can not get hold of a actual person to assist me with the problem. Emails, with no reply messages, phone calls to system operated voices. So is all of FNB now automated, I WANT MY MONEY BACK IN MY ACCOUNT ASAP!!! A PERSON TOOK IT, SO PUT IT BACK, o yes I have been to a branch, and no I have to call *** no answer, emails with no luck, or will some one in FNB offer to pay the things I have to pay??? this is unacceptable, poor service, arrogant of the highest level,<br> HOW CAN WE HELP YOU????? GIVE MY MONEY BACK, THERE IS A START!!!
