Hi @NIYOCOMM20260217S3UY Kumar,
Welcome to the Niyo Community! 
We understand why this would feel upsetting, especially after you’ve already cleared the bill. To reassure you, if your payment was made within the due date, your account is absolutely fine, and there are no overdue charges or penalties.
Please note that these emails and messages are system-generated reminders that can sometimes go out around the billing cycle, even when a payment has just been completed. We agree this isn’t ideal, and your feedback is completely valid. We’ll be sharing this internally so the communication can be improved and unnecessary worry can be avoided.
Thank you for calling this out, and we’re sorry for the stress this caused.
