Opinions on whether or not this logo is considered a copy

[ZDesigns]

I recently made a logo for a build team. The client was concerned that this logo is considered a copy, which will poorly reflect on their brand's image.

My argument is that I used basic concepts and combined them to create a unique logo. The idea was to have an isometric "A" with a piece taken out of it to represent a Minecraft block.

What are your opinions on this matter?

Note that upon the client's request, they will be refunded. Additionally, this logo is now for sale; pm with offers.

You sent them a sketch prior to completion though right? I don't personally see a problem... The idea clearly translated to completion

Yep, sketch was exactly the same. Only thing that the sketch didn't have was the lines in the missing block portion.

When it comes to illustration its of much easier to say if somethings a copy, since things are more complex/detailed usually,
(so like if i were to compare the look you have for your design and that other logo to an illustration, it would be like taking a portrait drawing, and then changing some facial features a bit and maybe adding glasses) but for something as simple as a basic square flat design, there are not that many choices one can make, the designs are gonna get repeated, many times not even intentionally.
I do wonder, if removing that bottom plane from that middle missing chunk would make it look better, would be less like the other logo and look more like an A since an A has an empty hole in the middle... I'm just rambling at this point, sorry xD
