Refund I do not how...

good morning
Last week I bought a topic that I attach below
I don’t see how I can return the item because it doesn’t work on my server.
I have contacted the house and they do nothing
I would like to have help
theme is

Doxwell : Physical Therapy WordPress Theme

Regular License 6 MONTHS SUPPORT


I have checked that theme and I think better you can contact support before refunding however you can request a refund by clicking the link below:

Not sure what the problem is but you need to contact the author first. If it’s related to the theme, you may ask to update it first then you may be eligible to ask for refund

If “the theme is not working” because you couldn’t install it or manage it, you’re not entitled to get a refund and the author is not responsible for these issues, by the way
