We want this fixed as much as you do, @since2007. 

As of now, our engineers are still investigating the cause of the issue. Rest assured, though, that they're doing their best to come up with a fix as soon as possible. 

I recommend contacting our  QuickBooks Payments Support Phone Team. so that you can be added to the list of affected users. This way, you'll receive email updates of the investigation's status and be notified once it's been resolved. 

I suggest you open this article as well: Process payments in the Merchant Service Center. You'll find steps on how you can process a credit card and an eCheck. 

I'm also including some additional info on Merchant Service Deposits in QBDT: Record Merchant Service Deposits.

I'm just one post away if you need a hand with Merchant Service Deposit or any QuickBooks-related. I'll be here to ensure your success. You have a good one.
