STANDARD BANK NOW FEELS THEY CAN LECTURE YOU!!!!!!

I have used my app for the last few months since opening the account to see payments due etc. I have never missed a payment on my blue bean card and in most cases have paid more then installment due. This morning i get a call to say i am overdrawn and was subsequently interrogated as to why. I explained to the \ call centre agent"that there was funds available the day before and that if i was overdrawn it was my bank charges that had pushed me over limit"
