Hi,
The SEF URL is generated dynamically on each listing based on the current menu item, the category that was used to access the listing of the products, etc.
When the Google Products plugin generates the URL, it's either from the backend or via the cron task. In both case, there is no "current menu item" and thus no way to generate consistently the same URL that you have on the listings of your website.
The solution is to properly fill the "canonical URL" field of your products with the URL that is commonly used to access the product page (and that you want to be used) on your product listings.
That way, the Google Products plugin will use the canonical URL.
That will have the added benefit of avoiding duplicate content issues with your product pages so it could even improve your SEO.
Finally, disabling the components folder in your robots.txt is not what prevents Google from using the link
mydomain.com/index.php?option=com_hikash...k-uhd-blu-ray-player
So it must be another rule of your robots.txt
Looking at the robots.txt file on your website, I think it is these rules:
Disallow: /*?
Disallow: /*=
