Repairing Fightstick?

I have a Madcatz TE-S Round 2 fightstick, but the warranty has run out since I've had it for more than 2 years. In that time span, I got a puppy and he managed to get a hold of the wire and now I cannot play with the fightstick. There is a visible tear revealing the wiring inside and it is clearly severed. Is there a way I could repair it?

I contacted Madcatz support already and for some reason they do not understand my problem...
