I bought a house in December & before moving I switched provider or so I thought. Bulb was the vendors provider mad they have blocked each attempt I have made to leave them. Last month I got hit with a £350 bill on top of the £111 that was apparently the agreement with previous house owner. This month after being blocked again from leaving I have received a bill for just under £1000!!! I live alone & am energy conscious. You can’t speak to them on phone states Covid reasons and the chat box I finally spoke to someone who said it was sorted and I’d receive an updated bill but I have been sent the same bill again. This is ridiculous!! Absolute crooks
