Is There a Process to Request a Refund for Signal Subscriptions that Do Not Function or Get Support?

 
I am new to the MQL5 site and subscribed to a signal.  The signal worked for a few days and then stopped.  Two requests for support from the author have gone unanswered.  I would like to know if the site has a process to request the subscription fees be returned either in full or pro-rata.  Any help here would be appreciated.  I suspect a request to the author would yield the same results as my request for support.  If no site level process exists, it makes me very concerned about investing further in subscriptions on this site.  Thanks.
