Do Not Volunteer Here

I had a terrible experience volunteering in Tanzania through Love Volunteers. I stayed there for a month with two of my friends. We are teenagers who wanted to do some good service work abroad. However, throughout the month, we were continuously lied to by the head of the NGO we worked with. He lied to us about how big the impact each project would be (turns out we spent 4 days installing a water system for a school only to find out that the purpose was to eliminate a 30 second walk for the students), and lied to us about the costs of the projects. We brought money to pay for the projects, and he give us ridiculous prices for all the supplies. Even his own employees were shocked when they saw how expensive he claimed the supplies cost, and they said there was no way those were the correct prices. Still, he took our money and probably most of it went into his own pocket. Several times throughout the stay he showed extremely aggressive behavior towards me and my friends, and yelled at me several times just because I would ask him questions about the projects or prices of supplies. When I reported all of this to Love Volunteers they promised to take action, but in the end they still decided to keep their partnership with this NGO. Do not volunteer here if you are looking for meaningful service work, or if you don't want to be taken advantage of.
