Loan paid into wrong account!!!!!

I spent the whole of last week applying for a loan, i changed my banking details, i verified them, uploaded my 3months bank statement spoke to Koketso, Marcel, Michelle and the rest of the GetBucks people and after i specifically told them that i have changed my banking details they still go and pay the loan into the old banking details. I have never dealt with such incompetence in my life. it was a simple request which has now turned into this big issue because they dont listen. their process is supposed to take an hour yet i spent a whole week applying and they still get it wrong. i had updated my banking details on my online application profile and now that someone on their side has messed up they have gone and changed them bank to the old details which are not even verified. i seriously cannot believe how messed up this company is. their online support is also not very helpful. i told them that i now use a cheque account and gave them my new details, they said the bank could not verify them, yet thats where my salary gets paid so ya, since the bank cant validate them you decide to pay to my old account. nobody even called me for the voice contract...this company though....
