Hello Edgard, I was in a worst situation than yours with my previous host canaca.
They advertise alot on google and one day I clicked on an ad. Canaca plans looked like a real bargain, 200gb of bandwidth and 10gb disk space for $3.95 per month if you pay 2 years in advance.
I decided to move on, the first two months went smoothly (traffic less than 1.5gb/month), but suddenly in the third month (traffic about 2.7gb) they suspended the site without letting me know, when I contacted support they alleged server overload by php scripts.
I cancelled my account immediately, by the way it wasn't easy. You know the old saying "If it looks to good to be true..."
