Duplication of Billings

I have been on the month to month package for the last 2 years. They debited my account on the 25th with the monthly subscription as per our agreement. On the 26th they again debited my bank account. On the 27th I woke up to find a debit order from rain that bounced because I took initiative to move my funds from the main transacting account. I am not sure what on earth is rain doing helping themselves into my hard earned money as they pleases. I called them yesterday for a refund and instead of assisting me they decided to cut off their services. This is definitely very low and to say I am disappointed on rain would be an understatement. They have my money while I am not getting the service they took my money for. I am frustrated as I am not being assisted at all. The inconvenience they are causing me by not being able to freely enjoy the use of my account because of "*******" that help themselves on my funds is beyond me!
