Freezing my account without contacting me

This weekend I had to swipe my card for groceries, my transactions was DECLINED. I went to the Branch on Monday to find out what is wrong with my account, the lady said that my account has been frozen, I have been contacted numerous times to update my physical address. I told her that no one has contacted me for nothing regarding my account. She said that the lady who previously updated my cell phone number did not delete my old contact number therefore Standard Bank send me messages to the old number. How on earth is it my problem? My new contact details and email address is updated on the system but no one did any effort to try and contact me via my new cell phone number or email address. I'm very unhappy with the service of Standard Bank I received, I had to take off from work to go to the branch, I paid R17.50 for my parking ticket, the A4 page I needed to print and also to go onto the internet. This had to come out of my own pocket just because nobody could just try and contact me on my new cell phone number. I demand to get my Ucount rewards on the transaction I did at Checkers on Sunday, I refuse to pay for someone else's negligence.
