My article is ignored

The journal European Journal of Pure and Applied Mathematics has accepted my 
article after a peer review and asked me to send it in their LaTeX format.

I had a hyperref trouble with my LaTeX file. So I’ve said them that I 
withdraw my article.

But later I realized that the best thing I can do is to remove hyperref 
package.

After this I successfully converted my article to use their LaTeX package 
and send it to European Journal of Pure and Applied Mathematics again. They 
then said me that will publish the paper “this year”.

A few years passed.

It is yet unpublished and the editors of the journal ignore my emails, where 
I remind them that they agreed to publish my article but don’t publish it.

What to do?

Note that my article is available online (the submitted version has a 
different LaTeX template and some minor changes):
