Billing for services not rendered

I have been using rain for almost a two years. In August I tried to cancel since I was not going to require internet for 2 months and the Rain contract is month to month. The consultant convinced me that they will suspend my service for the period of September and October, I agreed to suspension. However, Rain did not affect the agreed suspension but continued debiting my account. Phoning or writing on my rain website hasn’t been helpful. I have as result cancelled the contract. It’s apparent the month to month is a fallacy and they do not keep their promises.
