They rang about electrical testing and tagging. I agreed to the service, they came and did it. They have since rung us multiple times advertising the same thing, apparently unaware that they literally just did it for us. I don’t know if they are a scam company or not. Surely if they were a legitimate business they would keep track of who they had called and done work for? Or at least after the first time they rang back after doing it, and were told they had already done it!
