Direct Axis false promises and don’t come back to you with your requests

I Steph**** Dreyer policy number: ********** 8927 took out a loan with Direct Axis on 2014/12/15 but it seems as that hey increased the interest rate every month or year. On their website it states that your repayments are fixed at our current interest rate for the full term of your loan. They never go up – no matter how much interest rates do. This is however false because how can my loan interest rate be 32% for a loan I took out in 2014. After I talked to them a lot of times and requested more than 5 times that they need to look into my account and send me detail of all my payments with interest over the last 4 years they have ignored it and the collections department keep on calling me not the claims department. I owe them not a lot of money but I want to sort it out as it seems they have been overcharging me on the interest for years now.
