WHY DOES MY AVAILABLE CREDIT SAY 37.00 DOLLARS WHEN I PAID MY BALANCE OFF IN FULL?

My balance says 00. I have a 300 dollar credit limit, i used like 260 but paid it back immediately, Now it says i only have like 37 dollars in available credit. If i paid my balance off in full why dont I have more funds to use? Shouldnt I have almost 300 dollars of available credit? Should I call them and ask?|||It sounds like your payment just hasn't processed yet, it usually takes about 24 hours. I would check again in another day or so and if it still hasn't posted then call them. Unless of course it's already been 24 hours, then you should probably call them as soon as possible. It could also be that there was a problem with the payment, if you paid by checking account, another card, etc. you could have accidentally entered a wrong number or there might be a problem with the other account. Good luck!|||A lot of companies place a hold on a large payment because they worry that it is going to bounce. So if you took out most of your credit line in cash, then immediately paid it back, they worry that you are going to do a "bust out" and try to withdraw more cash off the card before the payment has cleared (7-10 business days) and then they are out of nearly $600.They will probably place a hold for about 7 days but call and check, they might allow you to prove that the check isn't going to bounce by calling your bank to verify funds and release your credit line.|||Call and ask. My guess is your payment hasn't been processed yet.
