on August 23, 2016, Ardent called our home to offer a savings on the gas bill. they tricked my husband (a senior citizen) into an account with them. He had no idea they were switching us. I called to cancel effective August 30th. Their letter indicates you can cancel Without penalty within 30days. I spoke to Eric w/ Ardent , who reported to DTE (our current gas company) that we are canceling eff. Sept. 30. (over 30 days)
