Hello, I took a look at it, and there was a problem with the way the WKT was formatted. I already corrected the format and have displayed the polygons in Qgis. If you write to me, I can send you an image so you can corroborate the work is done, and we can chat about the format you would like the layer to be sent to you.
I`m an experienced GIS guy, if you`d like you can see some of my previous work in my portfolio here (https://www.freelancer.es/u/pablomandolesi ).
At you service
