We appreciate the payment you made on ___ for $__ and I can confirm that it was posted on the same date on your account. I can see here though that the payment method you used was via checking account. For this payment method, there is a clearing period with your bank within 14 days. It means that the funds should be in your bank account within 14 days as T-Mobile will collect the funds from your bank within the given time frame.

It seems that when the system tried to collect the funds on ___, they were unable to get the funds from your bank. If I may ask, did you already speak with your bank and confirm if your bank account was deducted for $____ by T-Mobile?

IF CX SAID YES AND BANK CONFIRMED THAT THE FUNDS WERE DEDUCTED

I truly appreciate the information and nothing to worry about. We will definitely help you sort this out. We can file a missing payment request to check for this payment so it will be posted on your account again. To make sure it will be processed, is it possible for you to send me a picture of your bank statement showing the deduction? I will closely monitor this request so I can give you an update from time to time.

These are the steps that I'm going to take to reach an answer to your problem.
That's a valid point. If I can make a suggestion, there is an article that might be helpful to solve your problem.
