The Higgs field is \begin{equation} \Phi = \frac{1}{\sqrt{2}} \left( \begin{array}{cc} \phi_{1} + i\phi_{2} \\ \phi_{3} + i\phi_{4} \end{array} \right) \tag{1} \end{equation}
with $\phi_{1}$ and $\phi_{2}$ carrying electric charge $+1$ respectively, while $\phi_{3}$ and $\phi_{4}$ are electrically neutral.
Under the entry "Higgs Boson" in Wikipedia, it states:
It (the Higgs field) consists of four components: two neutral ones and two charged component fields. Both of the charged components and one of the neutral fields are Goldstone bosons, which act as the longitudinal third-polarisation components of the massive $W^+$, $W^−$, and $Z$ bosons.
Before interaction between the Higgs field and the gauge bosons, the total electric charge is the total charge of $\phi_{1}$ and $\phi_{2}$, which is $+2$. After the interaction, however, the total electric charge is the sum of the charges of $W^{+}$ and $W^{-}$, which is $0$; the electric charge is not conserved. What is wrong?
Besides, if two components of the Higgs field carry positive electric charge, the whole space (even the whole universe) is electrically positive since the Higgs field permeates the whole space. This is very doubtful and seems not reasonable to me. Is this case true?
