Bad customer support

I've contacted customer care to explain my original capital balance versus the amount reflecting in the personal loan repayment account. None of the consultants could clarify this for me and they told me that all fees and interest is included in the amount reflecting on the repayment total, yet they adding interest every month. When questioning why the capital amount doesnt reflect all the consultants could not answer me at all, instead they pretend as if they cant hear me just to avoid doing their jobs. This is pathetic service and clearly an abuse of power by having people pay more then they should. One consultant was just breathing into the phone and waited for me to hang up, we cannot have such people working for a company that cannot assist us. We need people who can explain exactly what it is that we need answers on. Their stupidity makes one just so miserable and irritated that you end up letting them get away with it. But enough is enough, this matter needs to be handled properly and by people who actually know what they were hired for.
