Update logging and return statements in billing services

The commit modifies the logging level in the billing services from 'error' to 'info'. Moreover, the error statement has been modified to clarify that the subscription cancellation has possibly been done by the user. Also, it reduces redundant imports and beefs up the return structure in stripe-billing-strategy.service.
