So, may I ask; how long have these people been clients?
I think what I personally am trying to say is, sure, you may indeed be okay in a CONTRACTUAL sense of this situation. But in reality, if they have only been around for a short period of time, they are probably not happy, and that we can somewhat see that standpoint as well.
And I believe you are dealing with a very passive-aggressive person, as I mentioned. Texting to tell you she's upset, instead of saying it outright. Signing the agreement, and then "stewing" on it, and letting you know after the fact that she is upset. Classic passive-aggression.
