How to contact Microsoft Billing and Subscription?

I have spent over an hour trying to resolve a simple issue that has been ongoing for more than two weeks. I am extremely frustrated, and I am now being told to wait even longer while Microsoft engineers attempt to fix the problem.

I am requesting a cancellation and a refund because I have not received the service as promised for over two weeks, and I am still being told to wait without a clear ETA. What business expects a customer to wait more than two weeks—without any timeline—before resolving an issue?

I would like to cancel my subscription and receive a refund for services not rendered. I have wasted over an hour trying to resolve this, and the responses I’ve received have been inconclusive. The problem has persisted for more than two weeks.
