Cinewhoop HGLRC 03 - ESC Not arming

I’ve recently purchased a new HGLRC 03 cinewhoop from unmanned tech shop (4th March). Trying to get support from them, I was just flying and then landed with no problem. No crash involved

I then went to rearm and the front right ESC isn’t arming. I’ve checked to see if anything was blocking but nothing I can physically see.

Anyone have a number I can call or the best way to get RMA or repair. I’ve submitted a ticket.

Thanks
