Just rang Them to make a claim for Marriage Allowance. The couple concerned are not SA, just low PAYE income pensioners. Danielle, the madam who answered the phone, demanded to know why client wasn't claiming through PTA, she was most insistent - she NEEDED to have a reason why! I asked if this had any bearing on the claim: apparently she wouldn't be doing her job if she didn't ask.
Told her I make a few of these claims, never had this issue before, and would simply call again to speak to someone normal, which I did.
