TWO CREDIT CHECKS FOR ONE TRANSACTION

I have noticed that each time I increase my monthly ATM limit, Standard Bank does a credit check and it appears twice on my name. They now have a facility where you can change your limit on line. I did this a few days back and yes, again there are two entries checking my profile. I have changed my limit in the last few months 3 times because when you change it, they revert to the old limit at the end of the month. I now have 6 credit checks against my name and at worst it should be three. I disagree that this has to be done every time because I cannot be a credit risk if I want to increase my EAP limit. I want these entries removed from my credit profiles with all credit bureaux.
