IMDB wont let me add a contribution for my credits

Hi everyone.

So, I worked in a netflix series called "Thursday Widows", or "Las Viudas de los Jueves" in spanish, as an extras coordinator and "payroll man extras" (which means I had to organize their papers and make a payroll so they could be paid.

My IMDB credits are listed under Fernando Fiallega S. and in this one they mispelled my name and I appear as Fernando Fiallegas in the "payroll man extras" category. I've tried multiple times adding this credit and it always get declined and of course theres no explanation.
I've tried using "extras coordinator","payroll man extras" and a few variations of both.
I've tried putting the attribute "(as Fernando Fiallegas)" and same result.

I'd like to know if theres any email I can write to and send proof of my participation so I can get a real answer to whats wrong? Thank you and sorry if I'm missing something obvious, had never happened to me before.
