I had a nightmare situation earlier this year and couldn't get through to Joel at Robotoyz. Joel had always been super friendly and helpful, to zero responses at all. Had no idea at the time he wasn't looking after the store.
If you want to get in contact with them, try Stephen at sfreedman521@gmail.com who appears to have taken over for the time being. Can't guarantee he monitors that email either, but I hope it helps?
