I bought ChatGPT+ but it shows free plan.

I have purchased a ChatGPT Plus subscription. The payment has been completed, but I am still shown as using the free plan. Could you please assist me with this matter?

I bought the plus plan from chatgpt, which I reached by logging in with google. But there was no upgrade to pro plan. Is the problem caused by logging in with Google?
