Intermittent issues for 7 months!

I am writing to formally raise a concern regarding a prolonged and unresolved service issue that significantly impacted my ability to use my service for its intended purposes.

Since October 2024, I had experienced intermittent issues with making and receiving calls. Over the course, I contacted both Apple and T-Mobile multiple times to sea a resolution even went so far as to upgrade my phone at my own expense, under the assumption that the deice itself might be the cause of the issue. Unfortunately, despite numerous conversations over phone, chat and in person visits to T-Mobile stores, not one was able to provide a solution.

After conducting my own expensive research, I discovered that a "family Allowance feature had been active on my account, limiting me to only 60 minutes of call time per month. This restricting was never disclosed to me, and it appears to be the root cause of my connectivity issues. it is deeply concerning that after months of reaching out for support not a single T-Mobile representative was able to identify this. 

As a result of this oversight, I missed numerous important calls- including work-related communications, and personal calls involving family. This has cause significant inconveniences, stress and potential financial harm due to lost opportunities.

Given the severity of this situation and the duration over which it persisted without resolution, I believe i am entitles to a substantial reimbursement for the disruption and costs incurred, including the unnecessary phone upgrade and loss of service functionality for several month. I kindly request that my account be reviews, investigate the details and provide a fair and appropriate resolution as soon a possible.
