Unprofessionalism - Identity

I app**** for an Identity account +/- 1 month ago, after application i received a sms Your R750 in FREE vouchers + R750 identity account limit are waiting for you! tj lewin, take your ID to any Identity store to complete your application.T&C's apply. last week i received a called as i had not yet activated account and was told the same you have a R750 credit limit and have until the end of June to activate, i then went to the Identity store in the Promenade Mitchells Plain, cape town to activate my account, i was told that i only have a credit limit of R500. one questioning this providing proof of my SMS and the call i got the most unprofessional attitude from both the sales lady and lady that authorized the account, i was told its due to my affordability, then i was told to call the head office to question the credit limit. the consultant i spoke to advised that a credit check is done on my name weekly and that is why the credit limit has dropped... who is giving them authority to do weekly credit checks on my name, this drops my scoring and is not allowed. my wife works in retail and works directly with the CBA and advised me that my score drops every time a check is done by a creditor, so knowing they keep checking to drop my scoring not allowing me to get credit anywhere else. I WANT THIS ACCOUNT TO BE CANCELLED!!!!! i also give my wife authority to discuss this account with you, she can be contacted on **********
