Verizon Continues To Say That I Never Had An Account, I cant get tech suppt for data, still have tv

I had internet and tv service up until Saturday, when I lost the internet. Can still watch TV on one box, but can not get tech support because they say I don't have any history of Verizon services even after making 6 calls to Verizon Customer Service and spending nearly 4 hours on the phone. Does anyone know of a Verizon customer service number that may be able to assist??
