The court issued Chase and the attorney a Sanction because they could not prove that I have not been sevred with a summons. The process server just served me with a summons and then left does the summons have to have proof of service?

If you got served by a real process server, then they have proof.

There is no requirement for you to sign anything. If he handed you the paperwork, you were served. His word will hold up in court, as a legal process server, more than yours would.

You were legally served, the process holder fills out a form that he gives that says he gave you the paperwork, he may fill in your @ hieight, race and a little details. You don't sign for it, they merely hand it to you.
In some areas if you refused to open they door and they were talking to you though the door, they can merely attach it to the door or slide it under, ( just depends on the state)
