Blocked Card

I received a call from an unknown lady claiming to be from the ***** Dept and she requested I give her my personal details starting with my Identity number, I obviously refused and requested her as to what the call relates to but she refused to tell me as she needed to confirm that she was speaking to the correct person, I explained to her that I am not going to just give my details out to anyone over the phone, she then uses a threatening attitude of telling me that she is then going to block my card which she actually goes and does. Now yes I do suppose that in a way she was doing her job but I have had the same number for almost 20 years and have had an Edgars card for even longer than that, surely she could have dealt with the situation better than what she did and she could have verified where I used my card the last time and then maybe used some common logic to ascertain if she was speaking to the correct person or not, Working in a ***** Dept of a Company who`s customers pay your salary you should show them a bit more respect than what you did. You should also know better that people are not just going to give out there personal info to any Tom **** or Harry over the phone because of the High volumes of ***** being committed in SA. I had to be inconvenienced of going into a store and have them make a call to the ***** Dept to verify that my card was soft blocked, Great service I had from Bayside Edgars and the young Lady who helped me showed professionalism and was very helpful. The Lady in the ***** Dept needs to climb off her High Horse and go for more training.
