Need help with 3rd party unique toys Alberich figure

Hi all,
I'm currently getting a few 3rd party figures to make my Decepticon Headmasters army. I got the 3rd party Alberich figure from a Chinese seller on ebay as everywhere else I used had sold out.
I have an issue with the figures left arm. The screw isn't tight enough and the arm wobbles and hangs. It's not a major issue but will affect the figure in his alt shark mode when the arms becomes the leg. I Contacted the seller whi wants to see images of the break. It's not broken, just very loose and the screwcan not be tightened anymore. Does anyone have oideas how to fix this issue or any way of contacting unique toys for their advice as I had heard they do help customers out with defects.
