Staff at the call centre cannot advise you which option to take. They are not allowed to. You will always be referred to the estimator, exactly as you have been. They can explain the pros and cons of each choice, talk to you about other factors which may tip the scales one way or the other if there is minimal difference with the estimator but they can't say "you should take this one"
