I switched to T-Mobile a few months back using the plan where they pay off the rest of my bill. I didn't realize that I still had to take a few more steps to complete this and I found out that I still have an outstanding bill with Verizon. I have had this outstanding bill for a few months now. I don't want this to effect my credit negatively. I am currently on standby for the prepaid card that T-Mobile provides me with in order to pay that off. How can I prevent any negative action directed toward me?
Normally when you switch carriers under an offer like that, it requires you to pay the balance owed to your prior carrier, and submit proof to the new carrier that it has been paid. Then they will send you the gift card according to their promotional policy. If you have already ported your number from Verizon, you have already received your final bill. This is your responsibility to pay, within Verizon's payment policy. Verizon will turn this over collections. T-Mobile is probably waiting on proof that you have paid the balance off.
I agree with the previous response. Re-read the TOS of the T-Mobile promotion but make a payment to VZW. Paying the balance is the only way to keep it from negatively effecting your credit.
