I stopped using Airnex communications since 2008, after having received several bills, that included Germany-which I've had never used.I've written them a letter, that I'm not going to use their services-never!

Unexpectedly in October 2009 they sent me a bill as of $24.66 for calling Georgia, that I have no idea about.
I've called them, spoke to assistant Julia, said that I' ve never called Georgia-she promised to do something.
After that I guessed to call my AT&T and asked them to block my phone from Airnex-and they did it.

Next month -in November 2009 Airnex send me another bill for $24.66. I called them again and said again that I've never called Georgia. -It is not for your calls, -they said-, it is for stopping our services (!!!)
-So last time this $22.66. was for Georgia calls, and now it’s for your services stopped-what ‘s going on?! -The connection braked.

In December 2009 I received the next bill as of $26.66, including my late fee$2.00

Please, help me to stop this nonsense.
I can send you letters from Airnex communications, just send me the address
