I finally completed level 551 and did not get credit for it.

It took me several weeks to complete level 551.  I finally did and the game did not move me to level 552!

Hi J- Thanks for posting on King Care. I am really sorry that you have been experiencing some troubles progressing in your game. I have sent you a private message, so that I can check your account. 

As soon as you get back to me we can get this sorted :-)

Have a lovely week!
