Making changes without notifying clients

I signed up 4 months ago for a woolworths credit and store card both with a credit limit of R5000 each! Today i go i to the store and make a purchase of R229 and my card gets declined saying that i owe a payment of R90. I have debit orders running of my account and i dont see why i should make payment instore. <br> <br> Previously my account felll into arrears due to the stupidity of the consultant that assisted me who failed to set up a debit order. <br> <br> I have settled the arrears amount when asked yet when i come to make a purchase i get asked to go to customer services to see whats going on. I then come to know my credit limit has been decreased to R1090. <br> <br> I get intouch with the call centre and all d agent could tell me was that there is nothing they can do to help me.<br> I do not see why i as a consumer should suffer at the hands of a retail store that cannot assist nor meet me halfway yet it was one of their very own staff who excuse my french ****ed up my debit order application. Had she did her duty..none of this would have happened.<br>
