When corrected address posted online?

I signed up for California Lifeline.  I expected pink envelope but never arrived.  Finally I applied online then realized my billing address entered wrong.  I corrected the address online, but does not show in my billing address.  It stays old address.  Actually address is correct but apartment number is 102 instead of 132.  California Lifeline told me to contact provider to correct it.  

There is no live agent, no phone number.  What should I do?  My bill is supposed to be lower long time ago.
