Pathetic Service

In January 2nd i signed up for their services. i was not told that i need an ADSL line for this service to be functional as i thought i would use a router. on the 3rd of January i called them to find out how to set up the data, i was told i need ADSL line. i asked the guy to cancel because the i don't have the line and i thought i would use a router. He did and sent confirmation to have received the request. on the 7th of January i received an invoice, i ignored as i know i have canclled. on the 8th i received a cancellation confirmation stating that there are 0 panalties. Ever since i have been receiving calls to say i must pay, been asking what an i paying for because i cancelled a day later. no one is giving me a straight answer. Now i have received an email from Debt collectors that my account has been handed over. So pathetic. Account number *** i want this resolved
