Do not do business with this company. There is a whole thread miles long about how they steal from their clients.

Hello. I had to cancel my contract within 24 hours. They keeped charging my credit card without consent. All these crazy unknown hidden fees and double charging for action. Horrible company! I should've check on this company before signing up.

I believe you must provide a 3-month notice (read your agreement).
And they do not have to provide any notice to you at all. They shut down my location with 2-day notice and then cancelled my agreement retroactively. So I had the opposite problem.
