Regard: Technician, Marcus Ford, Blackburn Plumbing & Air of Eastern Oklahoma, LLC First, I must say that I have not filled out the survey you sent to my e-mail, simply because I do not like to do that sort of thing on my phone, especially since you say that by responding, I accept that my e-mail address will be made public. I deleted it, without even looking at it. Therefore, I do not know what kind of questions you asked. However, I would like to make my feelings about your service and particularly about Marcus Ford known to you.
