The correct method for contacting about suspended sites is to correctly reply to the email sent to you.
On this occasion I have removed the suspension - your site is infected with malware most probably from a bad plugin or theme on WordPress or someone has gained access from an outdated WordPress install.
Please review all of your files on 000webhost File Manager and anything that looks suspicious just delete it or do a fresh install.
If malware is detected again the system will suspend it again soon - so please review your files.
