Good day

About a month ago i reported ***** on my fnb account. 3 transactions was made within 3 minutes on my bank account R1000 R2000 R3000 then a decline transaction i immediately reported it on my app and also called in to customer care and repoted it. Now today a month later im still reaching out to fnb of which a lady send me a letter stating the bank will not refund my money. So ive had no money nothing for a month now after my money got ****** from my bank via card *****. Just over a week ago another strange transaction happend another R800 got ****** from my account via Virtual Card Transactions. Same process i must wait 14 - 30 days . So my money is now gone . Saving money in account only to have it ****** from a bank and i have been banking with all my live. I am totally disgusted
