Your Answer in your Question???

As I can see you are a very good Software Developer, As far I know and understand those who developed software niche they are good at programming. If for any reason if you purchased a tool addon service from another marketplace, which will enhance your capability and developing a very good software for your client; which will become benefit at the end for your own benefits and you haven’t got any required formulation over the service; it means you have not done proper research work on your duties.

Truth: Marketplace offers many addons if you didn’t get benefits; you need to try on other addons tools or create it yourself because you are a software developer. I know it takes time and requires lots of hard work and patience but still, you can buy other tools like similar or create it yourself for your clients.

Answer:
scammer never do scams on online until you get a lot of niche benefits from others.
if you call another scammer it means you don’t have any experience in the existing underworld of the internet marketplace.
All Marketplace are similar and alike.
You need to research before you place an order.

Still, if you are convenient in my words, kindly create it yourself for you so that you never been scammed by other marketplaces. Rest your mindset popup
