Lack of response from customer services

Customer service:

I have raised a query in January via three channels: Agent, email and sms. It is weeks later and I still have no feedback or resolution.

The issue: Over a year ago you removed my meter and replaced it with a box with no visible meter. Since then I have had estimated readings. On my initial query I was promised a person would visit the house to check. This has not happened. In addition to estimates being used for my account, the estimated readings are almost double what they were this time last year so my account is severely inflated at this stage.

Your call line cuts me off every time I call now and I cannot seem to reach a human. Your sms number does not work. Please can someone attend to this matter urgently.
