Charged interest on loan even though I returned the money

<p>FNB paid out a loan amount into my bank account, and I paid back the money into the loan account within the 5 days of the qoutation. However they are telling me that I owe them +R1500 because I moved the money from my bank account. so basically they are charging me because i moved the money from my cheque account to my credit card account. My question is what is it to them that I moved the money because fact remains I paid them back the money.</p> <p> </p> <p>Not happy at all!!!!! and i am getting tired of the constant dissappointments from FNB</p>
