Why do I still have internet if I did not pay my bill to Verizon?

Hi I own Verizon $40 for monthly for my internet. My due billing was on almost 6 weeks ago late & I am going to pay them on Tuesday because I get paid. When I purchase Verizon internet box set, they never give me a account number. When I contact Verizon buy phone, they never heard of me & I am NOT on record? What should I do?
But, what about my credit? Would it effect my credit? I use to pay Verizon internet with my debit card.
