Starting on or around 3/1/08 our DSL service went out due to Nationwide Internet system issues (which they do not deny). Over the next 10 days, they did not respond to any of my multiple phone calls/messages or any of my multiple e-mails (which they do not deny), forcing us to find another ISP. I have cancelled my account on numerous occasions with them starting that first week of March and I continue to get bills from them for that time period. Their billing lead person "Megan" refuses to adjust the account for their lack of service and lack of any response to my requests for technical assistance for almost 2 weeks (which they do not deny). They are claiming that I did not cancel until 4/10/08 which is not true. They simply did not note or respond to my many calls and e-mails in early March '08 when it appears they were having significant system issues.
