You mentioned that your website is getting indexed by Google, but what is your position in the search results?
Is it higher enough to get organic clicks? And if it is, then what is the search volume of those keywords?
For example, if your website is ranking on "laptop repair and it support Dubai" but if no one is searching this in Google, you will get nothing.
So, use some keyword research tools and find high volume - low difficulty keywords. Use them on your website and then see the change.
Also, have you considered writing blogs? It is one of the best strategies to drive traffic to your website. Write something similar to your service and promote those blogs.
And you can always look for ads if you want traffic without any effort.
