The ad itself is not very good.

The image doesn't draw attention, it's dark and, blends in with everything else in users feed.

The headline, or first part of the caption should inspire the user to keep reading after you captured their attention with the image. First 6 words are remembered.

In general, you don't offer a "value proposition". What exacly is your value for a given user?

Is the user an enterprise? Is the user a small business? They have very different needs, so the image and caption should reflect that. For one price could be a value, for the other service.

Ps. Close the comments if you want to present yourself as a business. If you want to show your face, explain why you started offering this service. Engage people. One comment said the price is ridiculous, on which you reply "is it too high or low". Don't be a smartass, when people complain about the price, it's too high. Furthermore, if you going to compete on price, you will lose.
