unlawfull debit order

In May 2019 I applied for an online loan at Loan Detector SA, the amount of which I applied for was for R5000.00. I filled in the application and sent it through, hoping they can help me as I was in need for this loan. They wanted the normal documents bank statements, copy of identification etc.. I then decided against the loan and did not go further with it. This morning I note that there was a R399.00 debit made from my account, all it said was ldetector....... with the amount, I phoned my bank to stop and reverse this which they did. I went then went to google and came across all sorts of bad reviews about this Loan Detector SA place... I phoned them and the gentlemen that spoke to me said i have purchased a 12 months package. I asked him how on earth will i purchase a 12 month package if i was looking for a loan. Please please see below and attached correspondence from this company. I can not pay for something they never provided me for... I urgently need assistance.
