I purchased the Premium package which allows you to send questions to Dr Jacobs. I needed clarification on one of the steps so sent a short question by email. The response was a copy and paste from the steps I already had. When i emailed them back stating my question was not answered, they told me i was allowed only 1 question per week. When i explained that i was not asking another question but simply seeking clarification, i was told to either follow instructions or accept a refund on the QA portion of my purchase. I agreed to the refund to which they replied: "Done. We have over 25,000 customers and you are the first to request a refund on the QA option. That is because our customers recognize the obvious: no other CBT-I program exists world-wide that offers weekly QA with an internationally recognized insomnia expert for $10. The same feedback from a generic non-expert sleep specialist at a sleep center would cost you hundreds of dollars. You have emailed us three times today alone. Please do not email us again other than your remaining sleep diaries." Unnecessary and rude responses which make me question the validity of the business.
