Worx cordless lawnmower not working (Witney OX28 Deer Park)

This suddenly stopped working last week. The batteries are completely charged, so the problem is not electrical. Comes with charger and batteries.
Taken to repair people and there was a three week wait. We were also told that spares would not be easy to acquire as Worx is Chinese.
If anyone wants as spare parts or thinks they might be able to it going, they are welcome, before this goes to the tip.
