NBN FTTC suddenly no internet (DPU fault maybe?)

[Toycrane]

I had nbn installed on 11/4/2020 and it was going fine but few days later i suddenly had no internet. i tried plugging the ncd into different phone sockets, tried different phone cables, resetting and power cycling both ncd and modem but no luck at all. on the ncd i only have the power and chain light on, both solid blue, just no dsl and internet light. i suspect maybe a fault on the dpu. can you please send a technician out for me.
