I have purchased a clean Joomla + Template install with minor customization to color. I have done this work myself before but i just didn't have the time to do it this time around. Knowing that the work can take 2 maybe 3 days at absolute tops, it took Templatetuning team 2 weeks to accomplish this. Template looked fairly decent but for one major problem. None of the external links worked. Every external link was broken and lead to a 404 page. After notifying the project manager i was told that it was because I modified their template (which i didn't) and that I can't have a refund because it was my fault.
Customer service is horrid. They are rude and they blame you for their errors. You can only email your project manager because they are conveniently never available in chat. No one picks up the support line and no one will talk to you in chat because they are not your project manager.
This is the worst service i had ever had to put up with.
In summary, I would not recommend Template Tuning to a friend.
