Ethos International appears to be a US based organisation trying to improve clean water access for children and raise awareness about water shortages around the world. So a customer service survey of UAE banks seems an odd thing for them to do. Presumably there's another UAE or Dubai based organisation called Ethos International that's unrelated to the NGO (non-governmental organisation) with website here...
www.ethosinternational.org
But it seems to be difficult to find any further information about the UAE version
Anyone heard of them?
