Atrocious uncaring service

My mom has a Provider Plus plan at Ackermans which is administrated by IUA ,and my experience in claiming has been atrocious To sign up is simple but to claim is a nightmare, my mom is the policy holder and I the beneficiary she passed on the 4th of July 2022 and at the 2nd of August 2022 I am still hearing that my claim was not sent for assessment because the details which I provided correctly was some how not captured correctly, no one got back to me to let me know anything I only get answered when I call them and yet the problem was theirs not mine perhaps I will get paid out soon or perhaps not I will just have to keep bugging then I guess. What these companies don't seem to understand or process is that the claimant is in emotional pain when making this type of claim and the back and forth uncaring attitude in handling the claim is really something that bereaved people cannot deal with, please simply the claim process so that others do not suffer the ordeal that myself and my family are having to endure.
