QUESTION! plug broken when removing

Need replacement of plug to the Sonohealth product.
Entered to charge, could NOT remove from socket, then fractured
no longer useable. Need a new plug. How to get?.

plug is a standard phone plug they sell at wallmart fairly cheap.

Were you able to fix this? The cable that came with mine had a standard USB mini connector, the same that I use for my Motorola Bluetooth earpiece and other non-apple devices.
