13 months no pension pay out

It's been 13 months since l app**** for my pension, GEPF has advised that my former employer GDE should create pension numbers for periods were contributed pension but with pension number on my pay slip. Z125 form was completed but nothing has happened. There is no progress at all. I have been moved from pillar to post. When l call GPAA, Im told my former employer has to fix my pension number first.
