Enbridge billing department made a mistake by overcharging me on an incorrect gas metre for over 10 years, and then made mistake again on refund. Approximately 4 and 1/2 months later (in the following calendar year), after I had deposit the refund check, they wanted the refund money back. When I tried to work with them to correct the amount, they have been unable to get the numbers right after one and half year sending the check! To cover their mistakes, enbridge put outstanding charges on my gas bills and ultimately accused me of not paying my gas bills for 7 years (from 2010 to 2017 - I had paid all my bills and the account had been closed one and half year ago). When I was questioning on what I was asked to pay, without any warning or clarification, enbridge cut off the gas supply, put me into collection, and consequently damaged my credit! After over a year, the imposed outstanding charges still remains in my gas accounts, and enbridge is still unable to provide convincing information and a fair amount to allow for closure of this matter. The have been harassing me with collection calls and emails for over a year. Recently, they started sending collection calls to my son who is a student and has nothing to deal with the matter. The whole experience with enbridge has been dreadful. I have filed complaint with better business bureau, ontario energy board, global compliance. Their responses have been twisting facts, and blaming me for what had happened. They have damaged my excellent credit rating. They are a bunch of incompetence and bullies. I'm suing them in the court.
