Unauthorised money taken from my account by Just Answer.

I had a problem with a suspected **** and wanted help. I contacted Just Answer for help and I was asked to pay a small fee that will be refunded to me, I think it was R14 and paid it. The so called expert could not really help me and said it looks like I was ****med, which I knew at the time. I wanted help and not conformation. Next moment R599 was deducted from my bank account without me authorised the payment. I also never accepted membership or joined the platform. Big if costs was explained to me I never saw that, maybe it was put in such way that I easily would missed it. I only joined today for a minute to try and explain that money was taken by them without me authorised it. I immediately cancelled the membership again before they take money from me again….. Now they say they are only a membership service. That was never discussed with me neither was fees discussed with me because obviously I would have not be interested to pay that kind of money for the kind of help I got….. I am so upset and unhappy. I am a poor man and they are doing this to me…🥲
