I lost my data.
Yesterday I used mudfish to download 8 GB file (my traffic balance at that time is 21 GB). After download, the traffic balance must be around 12 GB or 13 GB but I only have about 1 GB left and today my account balance is -0.29 USD. I turned off mudfish after download and don’t use computer until now and the account is used only by me. Please check my account, lost 1 or 2 GB is ok because maybe my mistake but I lost up to 13 GB traffic balance is impossible.
