Probably an ineligible entry

@Fran​ Hello Fran, I went through the instructions you referred to and tried to follow them. However when I'm in the edit page, there's no 'title deletion' option that according to the instructions I have to use for this particular request (please see the screenshot below):  

@ramin_s_khanjani​ - If this specific title does not have a "Title deletion" option on the 'Edit page,' the request will have to be submitted through this specific Contact form instead, for our editors to review further.

Important As our aim is to be the most complete and reliable source of movie, TV, and entertainment information on the web and in order to continue offering our users an accurate and trustworthy service, it is our policy not to alter or delete any kind of correct/factual information from our records.

According to IMDb's own guidelines, audiobooks are eligible.
