Finding messages, files, and users using search tools in Microsoft Teams Free
Hey there! Nice to meet you!
Based on your description, I would recommend confirming the transaction details first by signing in to your Microsoft account on account.microsoft.com > Order History > select the date range when you received the $159.00 charge.
Then please reach out to the Microsoft Billing Support Team for further assistance, as they have the tools and resources to properly investigate the charge. You may contact them through this link:
Type "Billing Issue" > Contact Support > Microsoft 365 and Office > Billing and Payment Updates > Confirm > Chat with a support agent in your web browser

Thank you for your kindness and understanding! Please feel free to let me know if you need anything else.
Best regards,
