Why did my intrest in my bank go away. the whole reason i put my money in the bank was to make money on my intrest....

I put my money in the bank and lost over 1k just doing that.. kinda bumed.
then i was making intrest, yay.. ill make my lost money back some day..
then 0% intrest & you have 0% intrest made... WTF????? where did my intrest go and why??? if i knew i was going to loose my money & my intrest i would not have trusted it in the great bank of CX..

Is this bank not a member of FDIC??? <_<
