“I brought my father in for Hearing Aid on May 3, 2021. It is over three month and no one from Landmark hearing bothered to follow up on his hearing Aid. Even though I called late June and requested a follow up call, yet no contact had been made and he still does not have his hearing Aid. If you are not planing to give this 88 year old man, his hearing Aid, please at least send us his prescription and let us know so we can get his hearing device from another place. ”
