The policies regarding service cancellations and payments can vary depending on the company and the terms of the agreement you had with them. In general, if you canceled a service and the company continued to provide access due to an oversight or error on their part, it is advisable to contact the company directly to inform them of the situation.
When discussing the matter with the company, you can inquire about any outstanding payments or fees that may be owed. They will be able to provide you with accurate information regarding your account status and guide you on how to proceed. It's always best to communicate with the company to clarify any billing concerns and to ensure that the issue is resolved appropriately.
