if it is still under warranty, I would contact them for warranty claim.
If it is not, I would contact them for support
If they have poor support, I would open up the servo, take the circuit board out and take a look at the soldering of motor to the circuit board.
If the motor solder is ok, I would look at the solder of receiver wire and signal wire at the back of the receiver wire soldering
