Unknown ***** transactions on all my FNB cards

On 1 an 2 November two unauthorised/unknown transactions went off my cheque account. I was told to block the bank card and order a new one at a cost of R150. On 7 Nov another transaction from the same *****ster went off my virtual bank card, I was told to block the virtual card. On 8 Nov my new bank card was delivered to me and I activated it. On 10 Nov I saw that a transaction from the same *****ster was done on the new card on 9 Nov. I again phoned FNB and they said I need to cancel the card I received on 8 Nov and order another one. This is absurd and I think that it is quite obvious that my bank account has been comprimised and not each of my cards which having their own card details. How long will this ordering and blocking ho on for? Two or three months ago I went through the same problems. Not once has the so called ***** investigators given any indication of how or why this happened, now it's happening again. FNB does not care if you are unable to access your money when cards are blocked, this trend has picked up at FNB, is our money really save in their hands????
