Hello my name is ***** ***** I will help you with this.
How often does your partner stay?
So not regular? None of his bills come there?
Ok - that may be their concern because of the joint account.
But apart from that link they have no evidence. I am sure they just want to clarify the position and the only way they can properly do this is under caution.
But you do not live together - they would need to show that you do.
I would not be concerned as everything except your account is separate and even for that you have a good reason.
Can I clarify anything for you about this today please?
Yes that is fine.
Does that clairfy?
