Hello @Holli69,
Has the switch stack been deleted in the Dashboard?
Consider unplugging the device, hitting the reset button 10-15 times (to kill any juice that may be remaining), powering on the devices, and trying another reset.
If the switches are in a stack, perform the reset on the "active" switch.
Also, if the switches are in a stack, consider deleting the stack momentarily (please mind any L3 SVI on the stack).
If you have DHCP available on any other the VLANs, see if the switches can come online using DHCP.
Lastly, consider taking a packet capture on the upstream device if possible. This will show us what traffic patterns (if any) are seen from the switches.
