How to remove duplicate Facebook business pages?

One of my clients, has many facebook pages for their business. Throughout the years, former employees have created Facebook pages for the business.

Now we are using 1 official page, but people are still using the old duplicate pages.

I have already reported the pages many times, but nothing happens. Messages have been sent to the duplicate pages, to remove, but noone has replied. These pages are not actively managed.

Is there a easy way to remove duplicate Facebook pages for businesses?

If anyone has any suggestions, or service, I am willing to pay once it's done.

Call facebook and enroll to 1 month ads campaign. They will handle the rest after you verify your business with documentation.

If the business's logo is being used on the pages, simply DMCA the pages and FaceBook will remove them for you.

ioerror's suggestion can be very feasible. Having the pages subject to DMCA can totally help you do the job. However, if you want to make things simpler for yourself, consider giving Facebook a call and ask them for help. They will most probably suggest you to avail of their ads campaign.
