Why am I not getting anything sent to my verification phone number?

Why am I not getting anything sent to my verification phone number?

I've been using it for years.  Not sure how I'm supposed to verify myself if I don't get anything from you.  Are there other ways of verifying for people that don't use traditional cell phones?  Mine receives texts but is more of a VOIP line.  How do older people without cell phones ever use your services?  Many have business to conduct.  As I can't verify this account I don't think I will get emailed if there is a response here and if I did I couldn't read it because I can't even log in without verifying myself.  An endless loop of insanity.
