Biqu H2 V2s Revo dead after 3 months use

[Bappi]

My H2 V2s Revo was working fine last week 2 days ago I finished 2 prints off and this morning switched it on to reprint one of the files previously printed and get this horrible grinding noise which  I have now got on camera.  It had done something similar a few weeks back but that was a partial clog and the gears were chewing up  the end of the filament still inside the housing but it didnt make this amount of noise. I Also found this wear on the underside of the lever gear.

I have exactly the same problem after less than 6 months and have been trying to reach BIQU support for a few days. Unfortunately without success! Is there someone at BIQU who can help me to fix the error and get the extruder back in operation?
