It has been mentioned on here, on a number of occasions, that one should always always get an important interpretation/ruling from the CAA in writing.
It wouldn't be the first time they change their mind and/or subsequently say they didn't understand the question and/or say the person telephoning misinterpreted their answer and/or deny any knowledge of the question.
Some people even phrase the question to them to obtain the answer they want.
As has already been been pointed out to the OP, several times, she should simply get the definitive answer form the CAA in writing.
Maybe we can leave it there.
