Poor service

I had a very bad experience with this company looking for a personal loan. We were discussing detail on my application and they asked me to approve a debicheck on my bank and I asked them if there will be a payment as we were still busy finalizing details and they said no until the application is successful. They charged me R700 for a credit check where I could have gotten it for free on so many platforms. Now they said I agreed and do not want to pay back my money. Very disappointed with their service
