sum of complex sequence

Assume I have an infinite sum of complex numbers that I express in
polar form a_sub_n * exp(i*feta) where i is the imaginary operator,
Now assume that for a given set of coefficients a_sub_n that this
sequence converges to zero. Is there anything I can say about the sum
of all feta's?

Thanks for any pointers.
