Received a call from this number. Told me I could drop my rate from the Illuminating Co by 10% but I had to confirm my customer number. He had the wrong number and I refused to give him my actual number. I challenged that this was legit. He told me it was a 'computer glitch' and read the address associated with my account but had my husband's name. Bill is in my name. He obviously wasn't from the Illuminating Co and was very pushy when I refused to give him my account number or name. Then came back and offered a 30% discount. Claimed supplier wouldn't change it was just a discount for always paying ontime. Hung up on him.
