Supreme Lending

I received an email from Thomas Dutcher of Supreme Lending based on an inquiry I submitted via Costco site for refinancing options. His estimate provided a quote of 20 years (240 months) and the rate was not good so I politely declined. Here is his response:
«I gave you a 30 year loan option, do you know something I don’t? Rates are going up and will be that way for at least a decade or so. «
A follow up email stated,
«Rates are the same on a 20 year as they are on the 30 year so I am sure you can figure it out from there. I will remove your information, saving money isn’t for everyone…»
Very unprofessional and hostile with a superiority attitude. How can anyone predict rates by 10 years? Is this a sign of a person who is customer focused and reasonable?
