Still says it's a Starter Account after payment went thru?

So I have been playing WoW and I made a starter edition account and have been playing it the last few days. Today I hit level 20 so I decided to pay the 1 month subscription for full account. My coins are able to go past the S.E’s 10 gold coin limit now, and I am level 21 so the subscription seemed to work at first. But then when I go to try to capture a battle pet, it says I cant do that because I have a starter edition account??? I dont understand??? The payment came off my credit card, and I’m able to go past level 20 , so why is it saying my account is still starter edition when I try to tame/capture battle pets (the baby wolf things lol). The battle pets are a big reason why I paid $20CAD for the subscription :confused: so any help would be greatly appreciated
