Incorrect Debit Order Date

This Company "Finance 27" are ********* that exploit customers at their time of need. I got a loan from them of R1300 at the beginning of May and had a clear agreement with them that they will deduct they full amount at the beginning of June as i get paid on the 5th of every month. To my suprise 5 days later i get an Sms saying i need to pay the amount of R1700 that same month on the 24th of May, i called them them they consultant was useless she told me there is nothing she can do i mean how i can i take a loan on the 15th of May and be expected to pay it back on the 24th when i clearly stated that i get paid on the fith? They consultant claims that she does not know what happened yet i sent through all my documents reflecting when my salary comes in monthly she was quick to call out the blacklisting threat, this is the most shady FSP i have seen to date, iv got a legal representative looking into them i will not be bul**** by them! Stay away from them !
