Grant Funding Source They do not want to cancel a trail subscription by telling me thay do not find my info. but they already charge my bank account. they keep asking me to call back every 2 hours just to find the same an Internet

I was browsing on the Internet and saw an ad which said to get a free computer free of charge. Therefore; I went to check this out and in order to get that free computer I was suppose to registry for a free trail out for different companies I was suppose to pick 2 of them. Grant Funding Source caught my attention because it said They will give me all the information needed to get free money from the government and was so naive to register and give my bank account information. They charged my bank and when I read the fine letters at the button of the ad; I did not like what I read and proceed to call the company in order to cancel my trial out., they charge my bank account with $1,87 cents and after 14 days they will charge my bank $59.95 per month unless I notify them. They claim that they do not see my account information and ask me to keep calling every 2 hours. I have call them several times since yesterday with not luck whatsoever; I keep getting the same answer to call back in two hours and still they do not find my account. When I ask them how come they were able to charge my bank account they say that they do not know. When I ask to speak to a higher authority they say they all are assisting other clients and do not let me speak to any body. I got surprise to fin out in the internet that this is a rip off and I am caught in the middle of this fiasco.
