Never ending deductions from my account even after I have cancelled their services

These guys are ****mer's, be careful before you subscribe. Its so easy to subscribe but it is not easy to cancel the services.

My story goes like this, I have cancelled my subscription the past September and I ask them not to deduct on October and they deducted anyway. Then I called them to ask and I was told that they needed to deduct for October because my services were billed on a postpaid basis. I was like okay its fine, they deducted on the 15th of October and they send someone to fetch the router. Now on the 15th of November they deducted my account again and they are telling the same story they told me on October. The worse part is that once they deduct your money, you cant reverse it. PLEASE NEVER USE RAIN EVER IN YOUR ENTIRE LIFE. I AM SO ****ED OF AND I WANT MY MONEY BACK
