What do you actually mean by "but has ignored repeated emails (months) to make final payment of $570."
I actually searched it in google and it returns only issues like the one you posted here but in different Forums.
I have emailed you three times the last month, trying to find a solution. No response from you. Please contact me per email if you want to solve this issue. If not, fine by me, but you should definitely stop publishing these nonsens on the web.
Looking forward to hear from you, so we can solve this issue. Dot TK is a decent company that always pays for the services. There's always two sides to a story and I am willing to discuss this with you... as long as you email me back.
