I paid for ChatGPT Plus but I don't have access to it

I paid $20 for ChatGPT Plus 5 days ago now it’s saying I need to UPGRADE TO PLUS to use it. Who do I need to talk to in order for someone to change this error?

This is AIPRM, not OpenAI. ChatGPT Plus is offered by OpenAI.

ChatGPT is operated by OpenAI Inc., AIPRM is operated by AIPRM, Corp.
