I got the exact same call.
I also cancelled that bs 3 years ago, and now they are demanding a copy of the cancellation confirmation from 3 years ago.
I told em to fuck off, and I will see them in court. I will do some more research on who this is, and I will file a civil suit as soon as I found out more details about who this is.
If anyone has any details, please share so we can take these scumbags down.
