Searching for a repair shop in Europe for Ebit E12

Hey everyone, I'm feeling a bit stuck here. I've been trying to find a place in Europe to fix my two Ebit E12 hashboards for a few days, but no luck so far. I'm based in France and reached out to Zeusbtc's shop here, but they only handle Bitmain products, unfortunately. If anyone knows a repair shop or has any tips for fixing my hashboards, I'm totally open to suggestions. Just to give you a bit of context, one of my hashboards is working fine, but the second one is showing some temperatures but isn't hashing, and the third one isn't displaying any temperature readings or hashing at all. (P.S. If you know how to fix this or have any E12 hashboards for sale, please feel free to respond.)
