Unreliable bank

On Friday i bought my groceries at a Pick n Pay in Southgate andf i was told that my card declined, i took out cash which my husband had on him an paid for the groceries around R3700, I go to the atm yesterday to withdraw money and to my surprise the R3700 went through and i also paid cash, i went to Pick n Pay and i was told to sort it out with my bank as on their system is not showing, i need my money back, i want it reversed, i have activated the "MY Updates" more than once and had that sms system been coming through i would have received an sms to say that payment went through, i recently got a new card because the old one would not work on a Standard bank atm but guess what the new card is alo not working at standard bank atm but works on other atms, i now have to get charged for drawing at another banks atm which is not my fault.

on Friday the 25th i was at my branch Southgate for the 3rd time to get my new number( ********** 368) on my profile as i am unable to do any online banking because the OTP still goes to the old number i had which i asked Standard bank to remove from my profile 3 times. but still not luck the OTP still goes to the old number ending with 6276, i don't have access to my transactions i cant see even if something goes wrong with my account i am practically locked out of my account.

i need all of the above rectified as soon as possible
