I signed up for a one year membership with mademioselle and paid in full with a money order (I work for a bank and have seen the horrors of using pre authorized payments, or your own personal chqs to pay) They still insisted that I provide them with a void chq before they would honour my membership. I gave them a chq on an account that I closed many years ago so they couldn't take out any money.
I used the gym for 1 year then stopped going assuming my membership was over. 1 year after that I reveived a phone call saying I owed them a year worth of membership dues. They told me that my membership automatically renewed since I didn't cancel. Why they wait one year before trying to collect money..I don't know. Most businesses start trying to contact you after 30 days.
I went on the Consumer Provision Act website http://www.e-laws.gov.on.ca/html/statutes/english/elaws_statutes_02c30_e.htm and found that their contract violates many laws, whether you signed it or not. I sent a copy of this to their head office in Mississuaga, On and filed a complaint with the Better Business Bureau. Within days I received an email saying my membership was cancelled and the outstanding balance on my account was waives. Please DO NOT sign any contracts or pay Mademoiselle any money until you have read the info on the website above.
