The IPs were similar, but in an alternating sense, meaning it went from 10.10.10.10 to 10.12.10.10, and back to 10.10.10.10, and so on. It was very clear that Mayberry was ordering from two different locations, as you can't just reset your IP and then go back to the older one to my knowledge.
I would like to see the actual IPs. You can * out the parts that were the same or the first few digits if you need to.
Unfortunately, other than my bad wording of it in the older contract, this was not made more specific until the final, professional version.
Your new contract contains quite a few new problems. I advise you to take it to a solicitor and fix it. For example your repeated reference to penalties and fines are, for the most part, invalid. I have not read the whole thing but it suffices to say you need to research equity law and make your contract fair before any court would uphold it in its entirety. I would even go so far as to suggest you reconsider your business model in such a way that you do not need penalties in your contracts.
However, I can state that Corey definitely did not make the phone call. When I asked for evidence, I was desperate for anything, and even asked him and others to just take a screenshot of their Skype history where they called Mayberry, so we could show it to Google and say, "Hey, look, we called the number," but I wasn't even given that. Also, nowhere in the chat logs of the delivery that we have on our site does Corey ask to confirm Mayberry's number. However, Corey also took the conversation to his private MSN, so any records of that lay with him, which is most likely lost.
Absence of evidence is not evidence of absence.
That he did not provide you evidence that he made a phone call or SMS does constitute evidence that no phone call or SMS occurred.
That your website's chat log does not contain evidence of Corey asking for the customer's phone number does not constitute evidence that he did not ask for one; You accept that the conversation continued outside these logs. I have been given no reason to assume a phone number was not asked for.
To go any further:
I need evidence that he did not follow the procedures of your agreement.
That is, for example, evidence that according to your agreement:
1. He was not allowed to use his private MSN for closing deals, or
2. He was required to keep logs of phonecalls and/or other conversations with the customer.
You are alleging he broke your agreement. Of this, so far, I have seen no evidence.
Corey's counter claim is that you amended the agreement when he asked you over skype if he should process these orders. I have seen no evidence for this either.
So far neither claim has sufficient evidence to proceed. If it cannot be reasonably shown that Corey failed to follow the terms of your agreement then you may be liable to return his commission to him.
