My friend you are not on a site that sells or gives anything but freely gives love, comfort and prayers. This is a global prayer site attached to no ministry. It is not base in Africa.
Christian brothers and sisters pray for each other on this site.
But I must say that The Holy Spirit is a living being that heals. Bottled water is not an answer to your issues. GOD is! It is written that all men are appointed to die once. You must not blame any ministry for the death of your love ones.
God's will and your faith is the key, not bottled water.
Heavenly Father of the Most High, our God of mercy, I pray for this family. Lord place an hedge of protection around them, keeping them safe from all evil, in Jesus mighty name I pray. Amen.
