I applied for a Vanquis card a few weeks ago, simply just help me out throughout the month. The limit is only a small amount of £100, but after reading everyone’s comments I’m slightly worried about having it. I’ve used my limit already and the direct debit is due to come out on the 18th of this month.. If I pay back the £100 in full on the 18th, will I be charged interest? I’m stupid really because I don’t actually understand how these things work, I was just desperate for help with a bit of extra cash.
