Poor communication and service

Been with the company for years with no issues. All of a purple I start receiving messages to make deposits on what happens Tobe a debit order. I call no one picks up. I get told that I am arrears but no one calls to explain how. I complain about the service and ask for someone to contact me or I terminate the contract i get a termination letter that costs 3x the premium. Why or how, no one picks up to give answers. Then my account started getting double debits with no prior communication. Like I have no one to speak to nor getting sufficient communication other than emails not fully explaining the situation. The customer line just keeps ringing.
