Confusing Administration

I have consistently submitted my electricity readings from my meter over the years. I did the same with the company during a 12-month contract, and my invoices matched my records for nine months. In the tenth month, I received a demand for extra payment. After checking, I discovered my submitted readings were accurate, but the company claimed I had made a mistake. They later acknowledged that their invoicing was incorrect. I had to cancel my Direct Debit due to their error, which resulted in being put on a higher tariff. After reinstating my Direct Debit, I was informed of a new contract with higher rates. After further complaints, they confirmed my original contract would remain. Now I await my next bill with uncertainty about any further complications.
