Perhaps I should have mentioned which bank works this way. Standard Bank does not allow you to change your limit in any way but in the branch. They did not ask my husband what limit he would like when he received the card recently. Last time we had a debit card we set the limit to a high amount so why has it been changed to a random amount now?
I have asked Standard Bank in the past if they can temporarily change my limit and have it automatically reset at the end of the month but I was told they cannot do that and it will remain until I return to the branch to change the limit again. That limit was changed several months later without my permission. This is one of the many, many reasons that I no longer have an account with Standard Bank. I'm glad to hear about yet another thing I can do online with FNB since I have just opened an account with them.
So back to my original point; perhaps I should have said the bank card system is outdated. Credit and cheque cards generally are not given limits or are given very large limits so much so that it makes no difference. Why are you not asked to put a limit on all your cards when you receive them? Credit, cheque or debit it should make no difference. This nonsense of randomly making up a limit for me even after I have set my limit is outdated but on the other hand the other card linked to the only account held at that bank can spend enough money to clear out the account without even using a pin!
In fact the difference between debit and cheque cards is archaic and comes from the days when accounts each had very separate functions; either to withdraw cash, to spend on credit or to write cheques. Now everyone pays by card and cash can be withdrawn from any card. No one uses cheques any more, but even if they do there is no reason they cannot be drawn against one consolidated account.
One card (cheque/credit card type) can be linked to every account you have (credit, savings etc) and there is no reason for debit cards.
I have just moved from Std to FNB as well but the thing about auto resetting the EFT back to original at the end of the month is incorrect. They always do it for me, I set it at a higher limit and at the end of the month it goes back to the original limit. I have done it using three branches as well and over the last few years. Perhaps its just your branch. You can also request for your limit to be increased via the secure message facility on online banking. I have done this twice as well.
