Caller: Electricity - Cold Call

Phoned from a company who’s name I missed. They call from multiple numbers but all look the same except for the last digit. Basically just trying to sell electricity, explained I’m locked into a contract but he just spoke over me and told me someone would call tomorrow to make a time to come and change my lights and shower heads!!
Gee thanks! I don’t think I’ll be taking that call.

missed, left no message.
