Nobody called so I could unfreeze my credit instead of rejecting my application.

Quick and easy
Quick and easy, the cost is another thing. Gas, a natural resource FROM US I just think we are being way over charged for this. But that's my only complaint! Tech that came out was kind and quickly had my gas up and running and even .repaired a small gas leak I had! Great guy!

i signed up via their website (deposit refund)
i signed up via their website. first i qualify for not needing to make a deposit for being over 65, but the sign up process does not eliminate the process of making the deposit if you wish to complete the sign up process. so i made the deposit figure i can make the request to get my refund. do you think it has been that easy? NO! i called and first i have to wait till my term begins then they will process the refund. do i just get the credit back to my credit card i used to make the deposit? NO! i have to wait a couple of days to receive an email so "i can decide" how i want my refund. i didn't get my email so i called and then i got my email. the email says i have to create an account to the refund portal (not an account to my electricity account but another system - the refund portal) fantastic!! i am having fun. i click the link to create my account in the refund portal, and my antivirus software goes haywire that the refund portal website doesn't have the proper certificates and i should not proceed to website, so i back out. email says if i don't make a choice within some timeframe i will eventually get a check in the mail. did i say i was having fun??!! WHY CAN'T I JUST GET MY REFUND ISSUED BACK TO MY CREDIT CARD? CONSTELLATION HAD NO PROBLEM FORCING ME AND TAKING MY DEPOSIT WHEN BY THIER POLICY I QUALFIED TO NOT EVEN NEEDING TO MAKE A DEPOSIT!!!!!!! NO, EASY TO TAKE MY DEPOSIT BUT I HAVE TO JUMP TO 17 HURDLES TO GET MY REFUND BACK!!
