HI guys!

I really hope sonmeone can help, I am battling with the logic of my code. Here is the use case scenarion, we heavily use the call smodule in ZOHO, i have a workflow that triggers and schedules calls dependinf on the outcome of a call.

We have some contacts ( and by extension, Accounts) that dont have scheduled calls against them. We have few thousand Contacts loaded already. I need the code to check which accounts dont have any scheduled calls or any calls at all. I can get the checking for calls at all part right, but where I am battling is that if a contact has a completed call, but not a SCHEDULED call, the code is still picking it up as having a scheduled call, even though the call on that contact is in the past and has been completed. Below is the code, please can you help me understand where its going wrong.
