ABSA Bank review: services

I had a problem with my card which was unable to swipe, I visited the branch in balfour mall and I was told they don't do chip management. I went to another branch in a birchacres mall they helped me. I visited again balfour branch because my card was for some reasons not working and I was told its an old card I need to change it even thou the expiry date is next year july. Well I recently got a chance to go change my card last week whereby I went inside the bank at 15:18 but only left the bank at 16h20. The service there was very slow there was no que at all. They are just slow and only one consultant was helping in the inquiries. Well they gave me a new card and I also did a stop order to my 32 days notice account. I did not request for anything to change but to my surprise yesterday on pay day I went to the atm and I was unable to withdraw 4000 cos my limit was apparently changed to 1000 without my knowledge. Like seriously, after standing a que outside I get such an embarrassing moment to leave the atm without money. I suffered embarrassment in the shops when I swiped and my card was declined and still i'm suffering after I changed my card. Why was limit reduced without my concern?
