Blocked card frustration

I recently opened a foschini account and decided to to link my card in order to make payments towards my account easily. The process required a one time pin which was never received so I decided to call in and have the process done telephonically, the lady that I spoke to said I had to pass a security check which required the date of issue of my ID (I've never been asked for this info before), I had given all my details and to my surprise my card is now blocked due to failing the security check based on the date of issue of the ID, I've only ever had one identity document and now I have use my time and money to go to a store in order to have it unblocked. The online facility is clearly as waste of time as no OTP was ever sent to my email . I called in simply to have my card linked so I could have payments done timeously not to be inconvenienced by blocked card. Incredibly frustrated.
