I have not encountered any problems so far! They are very professional in their work (as you can see from this website).
Their support team is also great when it comes down to technical issues that they cannot resolve themselves - which happens quite often for our small business because we do lotsa SEO stuff :P So definitely recommend them if your looking at getting some good quality service providers who know what its about doing online/digital advertising :) Our main focus was keyword research but after going through all available options including social media campaigns etc., turntepage came up as one option where there were no other competitors around us within such an affordable budget!!
