Called at 10:47 on August 27, 2015. Thanks for those in the know letting us know this is ComEd promotions. I am annoyed by these spam calls. I have an unlisted number and block 250 calls. I still receive 5 to 10 unwanted robot calls daily. It is impossible to keep up blocking them. I have an ailing mother and I would like to have her nap undisturbed.
