i need a lawyer to sue a funeral home

my son past away 7/18/25 at almost 5 months pregnant and i took my son to the funeral home monday 7/21/25 and i called multiple times for my son remains after the cremation and i didnt get his ashes until 8/11/25 which made a month. I made sure they had all the paperwork they needed before leaving and they assured me it would only be a few days. I kept calling they kept saying someone will call and update me and they didnt so when i asked for the crematory information they refused to give it to me. I called the crematory today 8/12/25 and they informed me it should be at least two hand full of ashes when i got them it was only enough for a bottle top and that they said the only way it could of been that little was because they let my son decay before bringing him to the crematory. Im beyond hurt and mad this is all i have left of my son to be remembered and i want answers and a explanation
