Over Paying

I had Direct Axis loan for more than 10 years but this year i chose to pay back the balance and at least start saving my money without having to pay interest. I've been tracking my debts and my balance both on their statement and on Pulse since i know pulse falls under direct Axis. on the 11th of this month when i check my balance on pulse it was 615 and since i know i paid 900 few days back i knew my balance should be sitting on + only to be debited 3000 today on the 15 . I quickly called them and I was informed that the balance i see on my statement and Pulse are not the true reflection of what i should pay . so what I need to pay is hidden somewhere in their system and I should have called to know that. I am very shocked and disappointed to know that Pulse in there to mislead people to believe that they are on good record while the record is hidden somewhere and I feel like I'm being ****** by the company that have been loyal to and have been eating my interest for years. They are refusing to let go and telling me lot of stories . to them i should stay until the end on my contract so that they could continue ripping me off. Direct Axis should do right by their loyal customers and stop being greedy
