Holiday Savings On Line .ca HolidaySavingsOnLine,ca Billed my VISA 17.95 per month since October 2015 Montreal Quebec

No discounts received no coupons received no travel 50% off received. Basically got nothing from this 'negative billing' company. I have attempted to cancel by phone 2x. They do not keep records accurately (how convenient) and refuse to acknowledge this. They continued to bill my VISA monthly for 2.5 years; I had to cancel my VISA account. Waiting to see whether they continue to bill the new account. They refused to send me accurate statements of my accout with them by email or phone. Mike and Dorothy both gave zero satisfaction in discussing this on phone. I have emailed them 5x today May 1 2018 in order to demand cancellation and reversal of all charges to my account. I may end up taking them to small claims court. Have filed with Ontario Consumer Protection (*gov't of ontario) and BBB but BBB can't go after in Quebec. How do I ensure that I am not billed for anything in future from this company? Suggestions? They seem to have a way around the VISA system as I have 2x changed card number to new card. Now cancelled actual VISA account to stop them. This is unconscionable. They send out post cards in mail stating "Gas Discount" $1.90 per month and promising 50% travel discounts. Nothing received. Over $600 they have billed my Visa in 2.5 years.How can I get this back from this company?
