If you've only had your bp 2 weeks and have changed its environment that many times it is probably striking and not eating because it is stressed out.
Ideally everything should have been set up before you purchased your pet, but I know how you may be learning new and better techniques from the forum. We all learn from our mistakes
Now, if everything is right (temps, humidity, hides, water, etc) do not handle it or try to feed in for atleat a week. This will allow the snake to become comfortable with its new home. After that try again. If it refuses food again wait a day or two before offering again.
