The company is called Finet, guy we dealt with is Yasinn, Two phone numbers. 8508404515 and 0507 8502033
They have their Office opposite Home Prof. (The big D.I.Y store in Fethiye).
We have not been to their office as when we first got their details they came to us. However, we told our English neighbour about them and he did go to their Office.
All i can say is we get good service, internet connection is fine, no problems and we only pay when we are over.
So, we would recommend them.
