I signed up for GoDaddy $9.99/month hosting and after the first month this went up to $14.99 without notice. What is worse, is I called GoDaddy b/c my website is so slow to load (see: www.ommageo.com) and I wanted to know if they could recommend one of their VPS that would run my website faster - instead they said they would look into my current hosting and openly admitted there was a known issue with the shared server I was currently using. I asked if they would take my domain off the "known server with problems" and they said no, so I asked for a discount since I am paying for a service they knew was defective and never notified me - the rep. said I would get a 15% discount but that is when my price jumped from 9.99/month the first month to 14.99/month for the past 3 months.
