There are currently hundreds of Facebook members who can not access the Facebook Marketplace.  I have scoured the internet looking for solutions only to find there are dozens of groups on various sites discussing the same problem, several on Facebook itself.

I have reported this issue using Facebook's Help Center and all I ever is the same canned response, which appears to be the same for everyone reporting the problem.

          We received your report and appreciate your patience as we work to fix technical problems on Facebook. Though we can't update everyone who submits a report, we're using your feedback to improve the Facebook experience for everyone.

          To contact us about non-technical issues, please visit the Help Center.
          Thanks,

          The Facebook Team 

Facebook needs to fix this problem, it is not an isolated incident, I have bought several items via the Marketplace and it is very annoying that it has been over 2 months since I lost access with no reasonable explanation.
