Mackay was hired by Wigan just three months after the Football Association revealed they were investigating text messages, sent during his spell in charge at Cardiff, which he admitted were "disrespectful of other cultures".
With Mackay back in management so soon after being accused of racist, sexist and homophobic comments, the FA has been urged to come to a conclusion on the matter by anti-discrimination body Kick It Out, who issued a statement in which they also accused Wigan of "disregarding the investigation".
Wigan chairman Dave Whelan was also criticised by local MP Lisa Nandy in an open letter last week.
And the row shows no signs of abating after Kitchen firm Premier Range, which carries a logo on the back of the Championship club's kit, dropped their sponsorship.
"Unfortunately, their recent appointment of Malky Mackay has put us in a position that we find untenable," the Lancashire-based company said in a statement on the BBC's website.
"Mr Mackay is currently under investigation by the FA for sending text messages that are at odds with the general ethos here at Premier Range - and, it would seem, Cardiff and QPR feel the same as us.
"The texts Mr Mackay has admitted to sending are wholly unacceptable - and the thoughts expressed within them are a shocking reminder of a past we thought football had left behind.
"A team that would employ a man who expresses views such these is not the kind of team Premier Range wish to deal with."
