"Thank you for the update; I anticipate your response," you may say. A little stiff. But I would only say so if I was genuinely excited about continuing the written discourse. Otherwise, just end the note.
Most individuals would just say, "Thank you for your patience," or "I'm sorry for keeping you waiting." Thank you so much. Or anything along those lines. To my mind, the 'patiently' element of your proposed language is arrogant. It assumes that we are all patient and not to blame if we are not.
The only other option is to give them something free as thanks. Maybe a gift certificate for their next visit or something similar.
You can't really go wrong with either option. The choice is up to you what message you want to send out there. But I hope this answer helps.
If you have a "it," describe it. If you're writing from a customer service standpoint, you may just say "Thank you for your patience," unless you want to personalize the connection a little bit.

"Thank you for the heads-up," is a more informal variant of the statement. When you send a note of thanks or appreciation, it's also acceptable to use the words "thank you" and its variants such as "many thanks," "lots of thanks," or even just "grazie."
There are many ways to show your gratitude to others for their efforts. A simple "thank you" can go a long way, but make sure that you express your feelings loudly and publicly so that your colleague knows that you are grateful for what he/she did.
Here are some other ideas: give them a gift, call them up to say hi, invite them out for coffee, write a letter, etc.
Thank you for taking the time to express your issue. There is no need to answer because it is a concluding remark in and of itself. You may respond "OK," or nod, smile, or otherwise recognize the statement without saying anything, but chances are the other person will disengage with the closing phrase, so you merely need to follow suit.
