Final answer:
The issue involves a potential billing mistake with a service provider where a subscription was thought to be canceled but was later renewed. It requires contacting the service provider with evidence of cancellation and reviewing terms of the subscription for resolution.
Step-by-step explanation:
The question you're asking seems to relate to a billing or subscription issue with a service you've used. If you have an email confirming the cancellation of your subscription in January, but you were notified of a new subscription starting in March, this indicates there may have been a mistake or miscommunication in the service's billing department.
The first step is to forward the cancellation email to the service provider and request an explanation for the renewal notice. It's important to review the terms and conditions of the subscription, as there could be an automatic renewal clause that wasn't properly canceled. Keeping record of all communication and reviewing any bank statements for unauthorized charges will be helpful in resolving this. If the charge was indeed an error, the company should reverse the charge and confirm the termination of the subscription.
