Stupid outdated verification

Had an very bad and embarrassing experience this past 3 days.When to Bloem with my I.D to the Truworths store at the waterfront and they could not assist me cause I failed the verification question about what my telkom telephone number at home was that we had 24 years ago.Back in Kimberley I failed again because I did net know what the payment on the bond is after explaining to them that my husband pays the bond and the payment fluctuate depending on the interest rate.
