Bank *****

I have been a Standard bank private client for the past 5 years and a customer with them for the last 18 years. I have now on 3 occasions been the victim of the ********** use of my debit card-October 2014, February and most recently 2 days ago. Each time somebody managed to withdraw the amount of R 2000 while the card was in my possession. I do not share my pin or store it anywhere. Each time the bank simply responds that my pin has been compromised but clearly ******** s now have a new methodology but the bank refuses to investigate beyond the standard. I have again cancelled my card and asked for an investigation but am not hopeful at a positive outcome. I am now seriously considering changing banks.
