No it's not 

Thank you so much for your reply.

Last paid. To be honest I don't have a lot more info, I am glad to hear about the phone call.

Only 1 other debt - my current utility company - I am behind so they are offering a PP.

I will email Lantern with my address.

Is there a standard letter I should sent by post after?

Thank you again.

Hi, I was not of sound mind when I took a call from Lantern re: 6 year old debt but it happened.

They are chasing just under a grand, they offered it for 200, I said I had to go as working. 

They have since emailed me,

Am I right to assume they do not know my address so should I inform them in wring to avoid a backdoor CCJ?

Any advise is greatly appreciated, thank you.
