Character Profile changed from PC to PS3 system link

Hi, 

I have had an issue where my main character has lost all of its stats. Upon looking on http://www.battlefieldbadcompany2.com/ at my account it shows that the character is now a PS3 system link. 

I have never owned a PS3 nor run my account of a PS3. This character was originally linked to the PC and appears to have now been changed as there is no mention of my original PC character on my profile. 

There is a EA ID system link but no PC.

Can anyone explain why this has changed?

Thanks,
