Unfair Practice

I am writing to formally document my concern and request a final resolution regarding this matter.

As previously discussed, an account was created with an incorrect address and was later canceled. That account included internet service and a complimentary mobile line. I never requested or activated a standalone mobile service.

I can see that a partial refund has already been processed, which confirms that the charges were incorrect. However, there is still an outstanding amount that has not been refunded to my credit card ending in 2086.

At this point, I am requesting:

1. A full refund

2. Written confirmation that the mobile line is permanently canceled

3. Confirmation that no future charges will be applied
