I have been a customer for a long time. I have moved house and passed on details for the tenants so there is no interruption to Green Network Energy receiving payment. They still charge an early exit fee even though there is only four months to run on my contract. This is really poor. I am now telling my tenants to move provider. And they sent a rude email saying that I had cancelled my direct debit - of course I have. I have moved!
