Frustrating Experience with Unauthorized Contract Upgrade and Lack of Resolution

I am writing to express my frustration with the service I have received. Initially, I requested a cancellation and was advised to try the monthly option, which I agreed to. However, I later discovered that the plan was upgraded to a 24-month option without my consent. I only became aware of this after calling to cancel the service.

Despite my repeated attempts to resolve this issue, I have yet to receive confirmation that the contract has been cancelled. Each month this is delayed, I am required to make another payment. This ongoing situation is highly irritating and unacceptable.

I hope that by sharing my experience, the company will take prompt action to address this matter. The service I have received so far has been far from satisfactory.
