My colourblmbs and goldbars are all lost when I changed my device and also I passed up to level 2000

Hi @rizwanullah, sorry for the delay in responding and welcome to our community!  Were you playing the game through Facebook or the Kingdom because they save your progress on their servers.  If you haven't played through either one, I am going to suggest that you create a Kingdom account by following the steps on here: 

https://community.king.com/en/candy-crush-saga/discussion/250549/superstar-information-post-creating-a-kingdom-account-browser-with-images/p1?new=1

Once you have this account, you will need to get your user ID # and you can follow the steps on this link.

Once you have the number, please complete the contact form from this link:  https://soporto.king.com/contact

They can manually go into your account and get your progress back.  You will get an email with a ticket number.  Make sure to use this topic and subtopic when completing the contact form.

Regarding your boosters and gold bars, you should never lose your gold bars so once you get your user ID #, please let me know and I can have the community manager check what happened to them.  Boosters and lives are only saved to your device so that you can play the game offline. This does mean that any updates, crashes or device changes can cause these items to be lost. For this reason, we do not recommend storing too many of the won boosters as these can indeed be lost unlike Gold Bars.  You can read more about this here:  https://community.king.com/en/candy-crush-saga/discussion/177871/safeguarding-your-collected-boosters
