Breach of Contract

When the agent / consultant concluded the deal, she advised me that should it happen that I settle my account within 6 months, I won't be charged interest, the only amount that will be charged will be the loan amount granted, now I called sometime last week to request the settlement amount, I was given an amount which when I add up with what I already paid, exceed the loan amount granted, so I want to find out as to why is this happening? Is it your way of attracting people thereafter you don't deliver on what you promised?<br> Contract is a legal document, so I request Finchoice to honor it by giving me a settlement amount that will be equivilant to what was granted (inclusive of what I already paid). Kindly listen to your recordings and revert back to me urgently before I escalate the matter to NCR. Last week the lady that I spoke to advised me that someone will revert back to me, to date, that hasn't happened.
