Medihelp Manager still has not called me

I requested for a Manager to call me after speaking to a consultant on Friday 12 November, and he took my number down but no Manager has called me back. My mother being 5 years with them and we asking for simple things they still refuse to authorise. Saying they can't even if pay cash for the prosthetic. So I don't understand, the consultants are good in explaining though a manager can help further but I guess I wont ever get them to return the call
