My host said I'm not allow to use cron job, what can I do?

Hi,

I want to set cron job for my sport site to ensure that result and match updates are achieved automatically from the soccer engine plugin I used. However, I noticed that the premiereship league started yesterday wasn’t update and the author plugin said I need to set wp_cron. After a several research, I disabled wp_cron in the config.php and set up real cron job. However, after placing my email and update I saw; “you are not allowed to use this program!” Also, it shows json parse failed when I used my gmail. What can I do? How can I set real cron job not only for the soccer engine but also for autopost to social networks?

Regards
