promoted gigs bug issue Promoted Gigs

[sabirpro]

I have been facing the promoted gigs issue from the last month. As we know this is a automatic algorithm for promoted gigs but why the whole account d-ranked???? and why all the gigs stopped at once for promotion???? and ultimate results are d-ranked and put the gigs on the last page.  
My three gigs are in promoted gigs and there should be one gig to be went down when it doesn't meet the criteria but this is just my observation i think. Algorithm d-ranked my all gigs when promoted gigs stops. how to overcome this issue?? Please share your thoughts. 

Thanks
