We truly understand that you will be needing more time for this. However, we are unable to change the existing payment arrangement. I recommend keeping it in place to avoid suspension of service and additional fees. I also want to make sure you are not running into your next bill which will create a larger payment amount later if we delay.
But the good news is that, we actually have another way for you to get a new arrangement on a further date! All we need is to wait for the current arrangement to fall off that within 2 days and once the arrangement has fallen off, you can set up a new payment arrangement since you don't have any 31 past due balance yet! Is this gonna work out with you? 
 
I appreciate your kind cooperation with me! The good thing about setting a new payment arrangement, this will gives you an additional 14 days extension to settle the bill and it will also have a 2 installment option for the past due balance. 
Once the current arrangement fall offs, you need to immediately set up a new set of payment arrangement using this link https://www.t-mobile.com/support/account/payment-arrangement?cmpid=hw_send or using the T-Mobile application.  

Just let me know If you have any clarification with this, alright?

Due to the impact of the recent pandemic, we temporarily allowed the removal of the payment arrangement. However, as things are returning to normal, we have reinstated the original process for payment arrangements. It's important to note that delaying the past due balance can have a significant impact on your bill and payment history, which is something we want to avoid. Our goal is to provide long-term solutions for our customers, which is why we always recommend making a payment to reduce your bill.
As a one time courtesy, we will help you delete the existing payment arrangement to set up a new payment arrangement, alright?

Thank you for your patience, XXX. I can see that there is a payment arrangement in place for the remaining balance of (minimum payment), with today being the scheduled draft date. We understand the importance of extending the past due period, but unfortunately, we are unable to modify the existing payment arrangement once it has been set up. However, once it fall off on (fall off date), you will have the opportunity to create a new arrangement with extended dates.

It's important to note that there may be a partial suspension of service due to the original arrangement not being fulfilled on time. But don't worry, once the new arrangement is created, your service will return to normal.

I'm very pleased that we've been able to help you today by confirming the possible option to set up a new payment arrangement. Once the existing payment arrangement falls off, you can set up a new one using this link https://www.t-mobile.com/support/account/payment-arrangement?cmpid=hw_send. 
No worries, once the payment arrangement falls off, you can set up a new payment arrangement since you still does not have any 31+ past due days.
