Hello, I’m Nathan, and I’ll be assisting you today.
Sorry to hear that you’re having trouble with this but I’ll do my best to help you out.
That handset model is not available for purchase, it was part of the original bundled system only.
The compatible additional handset to use will be: http://amzn.to/2aKft0k
It does have a slightly different design, but performs all the same functions.
It will also come with the charger, which is the only way these are sold, they are not available individually.
If you have any other questions, just let me know. Otherwise, please take a moment to rate my service using the stars at the top of the page; hopefully I have earned 5 Stars. I also invite you to contact me directly with any future support needs at http://bit.ly/1QwLxGh and ask for Nathan.
Thank you, ***** ***** a nice day,
