Displeasure with Recent Tariff Increases and Account Cancellation Inquiry

I am writing to express my dissatisfaction with the recent tariff increases I have experienced with my account. Unfortunately, I have been trying to reach your billing department via phone, but have been unsuccessful in getting through.

Given the substantial increase in rates, I am now considering canceling my account. However, before proceeding with this decision, I would like to inquire about the cancellation policy. Could you please provide me with details regarding the cancellation process, any associated fees, and the timeframe required for cancellation?

I understand that changes in tariffs are sometimes necessary, but the recent increases have put a strain on my budget. Your prompt response to my inquiry would be greatly appreciated as I consider my options moving forward.

Thank you for your attention to this matter.
