On this website https://www.magticom.ge/en/useful-info/offices you see a map with a layers (4.5G, 4G, 3G and 2G) that are uploaded in Google Mymaps, I asked the company if they can give these layers but operators have no idea about that. Now I have to find other ways to get the layers for my GIS. Is there any possibility?

As I said in my comment, I reformatted your raw data. I did this with some python and a little hand-jamming. The resulting JSON is here: http://dl.dropbox.com/u/2654618/la_geom.json That's the Esri JSON format for a polygon. The link above converts the geometry from the Esri JSON format to the Google format, which is a two dimensional array.
It seems like there's a problem converting the response from SQL Server to the two dimensional array that Google expects. I would look at your code doing that conversion.
You can convert kml to other GIS formats such as shape using ogr2ogr, part of gdal. If there are too many points or double points this should not really cause problems: calculating a length is a fast progress.
Although they work with any GIS program, calculating the actual length is not that straightforward: most of them only work with projected data, and if you have global cables they should work with unprojected data as well.
BTW: a google search turned up with this tool to measure lengths in kml files: http://freegeographytools.com/2007/determining-google-earth-path-lengths

Ok, some quick hacking and I found they are just georeferenced KML images.
The KML file has bounding coordinates and calls the png image.

I would expect to see 2g, 3g, and 4.5g KML and PNG images from similar urls.
