Razer Dongle burn/bent?

Hi so about 6 months ago my Razer ultimate mouse (RC30-030501) my dongle stopped working. I didnt think much of it rather than its a software issue and it could be resolved that way. I had a kid around that time too so i didnt have much time to resolve it. 

Turns out, the dongle is bent and kind of burnt? It has melted a little and warped the black plastic where it says “2.4” also the metal piece was stuck inside the pc port so i had to get it out. 

I tried once again to download the Firmware software but it didnt work. 
Does it really have a unique pairing to the dock and i cant just buy a dongle off the internet and call it a day? 
Money is kinda tight right now so buying a whole new mouse is not it.
