Loyalty means nothing to capitec

I asked capitec to increase my credit card from 20k to 100k so I can honour a purchase order, which I would pay back within 30 days. But I was offered a revolving credit, that charges me the minute I use it. I just want an interest free credit like a credit card. I am not happy. I have 100k on your savings account, how can I not be trusted? I even bank with you. This is the pits.
