1. In October 2024,I bought a I Phone 16 max pro from T Mobile store for some other person as he didn’t have address documents and mail ID. I gave my documents for mailing address, mail ID and alternate contact number at T-Mobile store. 2. T- Mobile sold the I phone with a sim and monthly plan of $95. The other person didn’t pay $95 for the recharge after October. He kept using the phone on his home WiFi as the sim was active but with no service. 3. In March 2025 a 3rd party, not T- Mobile sends me an outstanding bill of $588.33 on the T-Mobile plan I took in October. 4. Now my issue is why didn’t T-Mobile inform me through my address Mail or my mail ID or through the alternate contact number that my plan was not being recharged and I am collecting an outstanding. Why a third party is sending a mail on my address to collect outstanding dues on T-Mobile plan. In between I was getting call from the 3rd party that I have an outstanding, I went to the T-Mobile store and asked should I entertain such calls they said it is spam, do not entertain these calls. 5. How should I go about clearing this Issue can anybody advise me on the steps to be taken. It’s concerning as $588.33 is not a small amount.Thank you all.
