****my and ************ **** contracts

I app**** for a Fibre line with Supersonic early last year. They were so slow to respond and never sent inspectors to my property, as the preliminary step. I cancelled the order and used a better service provider. For the next 10 months, they sent spam messages non-stop. Suddenly last week, they opened an account under my name and started invoicing me. They refuse to provide proof of an agreement, or evidence of correspondence. I have never known such an ********* and ************ company! The absolute worst!
