Call in and get a Tech visit - they will move everything to where you want it, replace cables and balance all the power levels.
You should be able to blag it for free as they sent you the wrong fitment as it wasn't correctly cabled when you moved in - worst case scenario though is a £25 charge for a non-fault call out charge
