Poor Service

I am utterly disappointed at the service I received from Johanna at Osmans Carnival Mall who failed to follow up with me regarding a frame for my spectacles. I visited their branch last week Tuesday on 07/01/2020 to find a frame, when she failed to find it within the branch, she promised to enquire at other branches (including the branch in Palm Springs) and promised to call me. I have waiting a week for feedback as I need to know what my action of recourse is regarding my frame. When I contacted her today on 13/01/2020 to ask why she hasn't called me back, she told me she was busy.

I am furious.
