Jesse Smyth - Retiree billing issues

Robin,

Original question:

Jesse called me earlier to try and get clarification on his billing. He told me that Workterra notified him that he would be receiving a credit. However, instead he received a bill for $1,600+ that had a due date of April 1st. Jesse said he tried calling a couple of time, but wasn't able to get a clear answer. This is 3rd time he has contacted me to help him with billing issues over the past year.

Current concern:

Client is now asking if the April payment covers May, and why and when did this change.

I believe to my knowledge that this client was always set up that way, but i do not know for certain. Can you please let me know?
