Reviewed doxo on Wednesday, May 23, 2018 I find better service paying with Metro Water Tucson Xpress Bill Pay than paying Metro Water Doxo! Doxo.com can't compete with Tucson-Xpressbillpay in Tucson ! The serchen customer ratings about doxo.com when you "tucson-water-bil-pay "say it all. 26 of 26 people found this review helpful. Did you find this review helpful?
