how can i fix this?

[abwttalal]

I signed up for the trial period. created the account out of curiosity and wanted to see if it would benefit me so I could really sign up and make it official, but I was busy and didn't have time to explore it until today I went in and found him asking me for a high price. so i cancel it immediately just for it to increase this much! I'm having a stroke (: i can't afford it! what can do? why is it cost this much?? can it be canceled since i didn't use the account?
