Please help me understand?!

<p>Why can't i reverse an amount sent to the wrong phone number?? The amount hasn't been withdrawn as yet because the recipients number is off and 3 of my attempts to remedy this mistake is proving futile. This was confirmed a team leader at your contact center (whom was wonderful by the way) except, processes are not working for us but for you. 7 working days is too long a time to wait for the money to automatically reverse, given that the other person could tomorrow, or another day, switch their phone on and i would have lost all chance to get the money back. This may be in your T&C's that you aren't responsible but are there no contingencies for a situation like this?? Does one then sit and pray to the heavens that the 7 days ends with no action from the other person?</p> <p>I'm in shock! </p>
