This is a company trying to get you to switch your electric billing to them as opposed to continuing with AEP.  The evidently have a computer dialing system that places calls faster than their people can pickup    I received 4 calls within about 2 hours before there was someone on the line.  The staff are very persistent and they only way to get rid of them is to hang up.
