Contact Czech SOLVIT here:
http://ec.europa.eu/solvit/site/index_cs.htm
IF they refuse to help you out (people have very different experiences with the usefulness of the SOLVIT network) I would strongly urge you to lodge a formal complaint (including the fact SOLVIT did nothing to help you!) with the European Commission here:
http://ec.europa.eu/eu_law/your_rights/ ... rms_en.htm
You can also get an overview of your rights as the spouse of a EU citizen here:
http://ec.europa.eu/youreurope/citizens/index_en.htm
OK, that's a few helpful links to get you started off. Please don't go back to Ghana before you at least put aside a day's work to sit down and compose emails to the different European bodies listed above.. if no one will make it clear to the European community just how far from the ideals the European project REALLY is, nothing will ever change.
With regards to working, you have every right to do so as the spouse of an EU citizen exercising her free movement. You should be issued a multiple entry visa if the Czech can't figure out how to issue you with a residence card within the alloted time set out in directive 2004/38.
Best of luck going forward!
Sincerely,
MSH.
