It does seem that this latest wave of problems, the trackless TX ID, is due to something that happened on 30th November since everyone's saying that's when they made the problematic withdrawal.

I still think it's worth another push. Send CoinPot another email/message. But this time try to be concise about your problem. And leave insults and personal sentiments off.

And just my two cents:

- Include the date when you initiated the withdrawal

- The dates when you contacted them

- Your user ID

- TX ID [and how it's returned in error or trackless]

- How much you were withdrawing

- Your Bitcoin address
 

That's how I would personally contact them anyway. Feel free to add anything if I've missed something.

And to just reiterate my opinion, no matter how much you want to vent your anger with insults, it might not help in this case. It might just aggravate the situation.
