My neighbors got my house ablaze

I lived at no4, oremeji street Agege, few weeks ago our supposed
landlord came to exhumed the corpse of his elder sister who was the house owner(original landlady) back to the story i heard about the house, the woman was married for so long with no issue, she built 4 houses in Agege Lagos, she trained all her siblings and set them up(biz) but this very brother of hers squandered everything given to him, after d woman's demise, there was misunderstanding how to share d properties, year after year the remaing sisters died, the man sold all d houses, this woman was buried in our house situated at no 4, oremeji street because she had already told all her family members that she must be buried there no matter what or where she dies cos it was her favourite of all her houses, 22yrs later (which was last month) this man sold the house n exhumed the woman's corpse, lo and behold d white cloth used to bury this woman was still as white as d 1st day with all d bones complete, this man had sold the house since dec last year without d tenant knowing anything, he just took 2 new tenants and force all d other tenants to pay advance of 6months rent, he sold the house to an hausa man, 21days after d corpse was taken, suddenly on a tuesday evening i was making my hair n heard my neighour shouting fire! help! we called fire service but it took them about 2 hours, before they came 14room upstairs, 6rooms downstairs was gone, the landlord said its none of his biz anymore, several complaint were made but it seems he prove to be above d law, he didnt refund the house rend people payed to him and now d house is burnt we couldnt get a pin out of d house, isnt that a babaros acts? Dear NL what do u think can be done( if there is any error pls kindly help me read with love n understand with passion as i type in pain without checking for errors) thanks
