Money exploites- Please help

I just want to know if other people are still experiencing this problem and what has to be done. In the month of march i was online trying to find a loan that will suite my needs. I came across a SA loan and completed my details. There was no loans given and I just got over it. At the end of April there was an amount of R359 that was deducted from my account and because I didn't know the service provider I reversed the payment. End of May there was a deduction of R94 which I reversed again, which was deducted as well. A week later I received a letter of demand by email from Jazeel advising that I need to pay R615 or they are summonsing me to court. I advised that I don't remember going into agreement with them or giving them any permission to debit my account and they should remove my banking details. I then get a response where Jazeel tells me they are not removing my details and I am liable to pay. When I asked what service was rendered I get emailed an online application. I then emailed back and told them I am not paying because I never received a loan and why should I pay for a service I wasn't given. Then I get a response that they are going ahead with the summons

I just need to know how to go about this. I am not in a position to be backlisted for a stupid company trying to exploit money from us. I have read reviews and I see a lot of people complaining but I don't see any resolutions
