We're not talking a few dollars here, we're talking a few grand. Making a large e-check payment to a company, they sent me an email saying "We got your payment" and all online metrics show that they did (lower balance, last pay date, etc) while the bank doesn't show the withdrawal (not even a "pending transaction").
I don't suppose maybe someone screwed up and I got a "free" 8 grand payment applied to my account??? Because that would be very sweet.
That happened with me when i first opened an account and deposited cheques. I assume its to build up a trust with you.
If youre really anxious about it, just phone up your bank. I memorized the processing times for all my bank accounts.
