Rifqiy Theme doesnt work mobile. Author MKRdezign doesnt reply.

I bought the Rifqiy Theme.
I installed following all the procedures.
On desktop works ok. But in all mobiles devices no!. Menu doesnt work, imagens not load.
I sent messages to the author MKRdezign, but he´s not reply absolutely anything.
The address he´s tell to contact him (https://satankmkr.ticksy.com/) doesnt exist.
How I can contact the author to solve thar problem? Or What do I have to do to have a responsive theme I want?

Seems he hasn’t responded to anyone in quite some time (2 years?)

Probably best to report this to the Envato Help Team and request a refund so you may find a new theme.

I did it.
Tks.
