Bad communication and Client service

I have been a client of Standard bank for the past 10 years. From day one I have received nothing but bad service. I'm still waiting 10 years later for my cheque card. I still have a temporary debit card with both my cheque and savings account linked to one card. I have during these years opened a FNB Account and received exceptional service. Always updating me keeping me informed and always updating my cards and accounts.The nature of my complaint is no communication from standard bank regarding my overdraft on my account being in arrears and then deciding for themselves to revoke and cancel my overdraft. Not to mention that this reflects badly on my credit record due to bad service and no communication. A courtesy call would have been appreciated and I would have rectified the situation immediately! I call in to find out what's happening and go through a 15min security check first. You do not need to ask me 10 questions to find out who I am! Only to be told they cannot help me and need to transfer me to another department who then asks you the security check AGAIN! Standard bank is useless I want to cancel both my accounts!! I'm not wasting any more money calling or my time!
