Great experience but would not choose EVOLC again

I was a volunteer teaching English to students who wanted to enter the tour industry. The experience was great because of the students but I would suggest going through another program like ISA or Maximum Nivel. EVOLC told us we were paying the lowest amount which we thought was fine because we were receiving little support. However, we realized other programs offered identical experiences teaching english but offered more support (prepping to teach English classes, cooking classes for volunteers, salsa dancing, etc) and charged $500 less. When we reached out to EVOLC/API they did not resolve the issue and just told us the money was "going to a good cause." Would not recommend EVOLC
