@JessicaLynn1969 (OP):
I just want to underscore the key takeaway (imnsho) up to this point:
That line item sounds suspicious and it is worth your time to investigate.
And add one more key point, which just occurred to me:
The fact that the initial rxn from at least three forum members was to speculate on its origin…that may be quite significant. Is this billing statement familiar to you? In terms of format, other content, timing, method of receipt, etc.? The document itself could be fraudulent. I.e., designed to lure you into a phishing scam.
The link I provided was pulled directly from Apple support so I am confident that it is safe for you to use (if it is Apple that you want to reach out to). Here it is again. Subscriptions and Billing - Official Apple Support
if you actually plan to reach out to T-Mobile or some other vendor, make sure you navigate to their website independently and call the customer service number listed there. For example, don’t follow a link or call a phone number that you receive by email. hope that makes sense. Please feel free to ask follow-up questions. And I think we’re all kind of curious to know what the deal is, so please feel free to share what you learn.
Good luck and happy 2024! (May it be AI overlord free!)
