2 Hours to get authorization

On Sat 04th of Nov, i went to ackermans store in kempton park for my usual shopping and payment of my account. To my surprise on this day the cashier needed authorization to continue with my purchase. I have been an account holder for ackermans for more than 3 years now, never missed a single payment. It took an hour from their office or call center to pick up the call from the store. And that was over several attempts to get through. When the cashier finally got through to someone, they asked the cashier to hand me the phone. The lady from the office started asking me all my information to update their system without even asking me if i would have time for that. Initially i thought she wanted my ID, tel/cell, and address to verify it was the correct person for the card but soon i realized she wanted to update the system. I I found that very rude, selfish and unprofessional. Why could not she ask me if i had time for that or if she can call me after for that. We pay for the parking at these malls and we needed to go to other stores as well on the day so it was very much inconvenience that I take 30 mins to gather my shopping and then have to wait on the queue for 30 mins and thereafter spend 2 hours on the till paying using their account. This simple shows that these stores don't care about the customers but about the bottom line and their profit. I am reviewing my relationship with this store now.
