I love the lighting but item is defected

I’m very dissapointed, I was looking forward to my first LED lighting to fancy up my new home. Unfortunately, after the 2nd of usage, half of the color strip won’t change the light to what I want it to, while the other half will. This is frustrating since now there are two different lightings. Furthermore, when I attempt to turn the color to blue, one part is blue and the other half shuts off. Please advise on this issue if possible.
