They ARE there at weekends but only answer 120.9 if there is operational helicopter flying in progress, the MATZ then being deemed to be active. If there is no reply after 3 calls on the 'official' MATZ transit frequency, the MATZ is deemed to be inactive however the ATZ will be active so steer clear.
If you really must call them at weekends, try tower on 127.150 or approach (non radar) on 130.250.
