Survey staff not getting what's do to them

FGI ( Judy Dryer) and Gweneth Lydia Hector does does not pay interviewers on the agreed date for completed work and they do not pay interviewers what is really due to them for projects. Tisa survey R100 per interview , interviewers only get R40 per interview . Genex Banking survey pays R110 and up interviewers are only promised R70 and up per interview . Genex survey completed months ago yet never been paid a single cent. Tabbaco institute of south Africa survey completed moths ago only been paid half the money . please be very weary doing work for either this company or Lydia
