Yo,yo faggots what's up?

So a short while ago I purchased this Madballs figure, it was shown in pics to come with the James Groman head sculpt but alas the alternative head was nowhere to be found.
I was wondering other than returning it and buying it again if there is any other avenue I could go down to get it?
Like if there's somewhere I could find spare toy parts for sale and such

Any help is much appreciated
