Fiverr does not guarantee your gig any sort of specific placement. There is no need to contact CS about this.
From the Seller Help Center:
“A Gig’s position in the marketplace is based on seller performance over a set period of time. Gig positions are not permanent and can rotate on a daily basis. There are many factors to take into consideration, some of which may include order cancellations, delivery rate, responsiveness, etc. There may be other Gigs currently performing at a higher rate than yours. If other sellers are ranked higher, they may be consistently getting 5 stars, delivering on time, communicating quicker, etc. This all counts. Make sure you deliver high quality, original work, avoid late deliveries and cancellations, be responsive and always keep a professional manner.”
