A huge dissapointment

Till this day I am still shocked at the way my case was handled when I called to get my cards cancelled. This was after I had tried widrawing from the atm using my credit card which is linked to all my accounts. To my shock my card was swallowed by the atm, this was an unexpected incident as I do not widraw money anywherelse except this particular atm. Having just walked from home to this atm, I didnt have my cellphone with to make an urgent contact to get my card blocked, by the time I got access to my phone multiple transactions amounting to R5000 cash widrawals had taken place already on my card. This again was the biggest shock as my daily limit is R3000. I asked the call centre agent who assisted me to cancel all my cards and I was assured that all my cards were cancelled. I then called again for the second time to ask for way forward in this matter and I discovered that my credit card which was used to make ********** transactions was still active. Really fnb? This was the shock of my life just when I was given assurity when I had first called that everything was cancelled. FNB investigate my case and please return back my money, This left me wt a huge question mark???
