I just signed-up and paid, but i got error-429. My limit is still untouched

I paid 5$ but I can’t access the functions. I already changed the api key and removed the limits and tried to contact via but the bot always responds. I could not get used to lemits as I have never used the functions. I tried to contact via api and Playground, but Playground says You’ve reached your usage limit. See your usage dashboard and billing settings for more details. If you have further questions, please contact us through our help center at help.openai.com.
and when contacting via api Error code: 429 - {‘error’: {‘message’: ‘You exceeded your current quota, please check your plan and billing details. For more information on this error, read the docs: .’, ‘type’: ‘insufficient_quota’, ‘param’: None, ‘code’: ‘insufficient_quota’}}

I’ve already tried everything in my power but nothing is working
