Didn't answer but got a voicemail from automated voice saying there's a fraud case against me (as stated before) and I'll have a warrant placed against my name, which they definitely don't know, and be arrested if I don't connect to one of their operatives. Made me chuckle.

Automated call stating it was HMRC and i was being investigated for fraud and to press 1. I spoke to someone who spoke bad english and lots of background disturbance on the phone. Told me I owed £493 when I questioned him how and why he told me it must be something from my end and could not confirm why. I said where are you calling from, he replied London. I said he would need to send me a letter to my address confirming the details he then hung up on me. These need investigating big time, bloody scumbags.
