That is very unfortunate. 😐
If you want something important done, do it yourself. Never rely on other people.
Go to another telco and get a different phone, cheaper than $900.

Learning the hard way is always expensive.
On the plus side, you'll never make that mistake again.

That’s why I never give it to the mail person. I want proof I sent it with a tracking number, or proof of delivery. Now you know your mail carrier is dishonest. You could report him/her, although if they don’t fire him/her, your mail may go astray.

There really is only one thing you can do... confront the mailman and I don't mean in an antagonistic way, but with a full presentation of the arrangement. Lay out what you said, what he said and sprinkle in how you trust him and you are not accusing him of anything. It may be naive, but maybe he just needs his memory jogged and the package is sitting at the bottom of his mail pouch or under the seat of his car. On the other hand, if he is being deceitful, you will be able to determine that from his body language.

On a parallel path, call T-Mobile and tell them the situation. They might not waive the charge, but will at least work with you to work out some type of arrangement.

And, next time check with me first. NEXT>>>
