Unfortunately Mr. Summers I can't trust what you say anymore, actions speak louder than words...
Props for the effort, now it's in the OP's court.
OP posted while I typed.
If there wasn't an agreement before these text messages (and we don't know when the messages were sent) then the OP had no reason to start the thread.
At this point all there is to do is wait to see if the cue maker makes the payments and any other defamation of character is unwarranted.
