A lot of patient advisors are very knowledgeable and want what's best for the patient, some are simply salespeople who only see a paycheque. It is hard to consult with a doctor directly (skype, Whatsapp, etc are available) if you`re going overseas but staying in your own country should not be an issue. Doctors should always consult with you prior to surgery, be that on the day of surgery which is usually the case if traveling.
If in doubt, consult with doctors from both clinics before proceeding.
