Absolutely appalling My tenant had Good Energy so I was with them by default until we found a new tenant. They came to MY home address - twice - to read the meter - under the stairs ... a bungalow! They then sent me an estimated bill for £202 - way too high given property was unoccupied. We gave them readings and they said they would send a revised bill. They didn't. Instead they had Credit Style - a credit agency - call me to chase payment twice, who sent me a chasing letter - I have never been referred to such an agency in my life. They finally sent out the corrected bill(£94.40) after giving them the readings again (acknowledging they had the readings on the system). After that another threatening letter from Credit Style followed - clearly the left is not talking to the right. Thoroughly stressful experience that involved many wasted hours. AVOID AVOID AVOID!
