i am utterly disappointed in the service

I took out a loan with these people signed a contract with them, they sent me to my bank to go and get 3 months bank statements, which I have to pay for mind you. This whole year I have been running after this so called bank because of them debiting my account on dates that we never agreed on.my 1st ref number for my complaint earlier this year is ***.now yesterday went into the branch in pta station with an aim to stop them from debiting my account on the 10th of December, cause there are founds in my account and got ref number ***8. The debit order still went off my account n now am faced with charges from my bank. I just need to know who is going to pay all those bank charges and fix the good record I had with my bank???? Am so hurt by all this I even rate capitec next loan sharks, where am I supposed to get money on the 10th of the month? Very disappointed
