Worst service Ever

I have been greatly disappointed with the service I have received from Momentum for my late husband’s investment. They having been saying the process takes 3-5 working days its been 3 weeks now and still no sign the claim being paid. The call centre department says something new every day from what the assessor says when I met with him. This is unprofessional and unacceptable especially from a woman mourning her husband. I have sent all information requested from them and from the 12 of November to date this pay out is overdue. Momentum doesn’t value its clients at all I am very disappointed by how this is handled.
