Unauthorized debit order increase

<p>I have been paying off my ABSA student loan from 2014 and since then I have never received a statement!!! I have requested a statement from them on various occassions with promises from different call centre agents that they would send me a statement but to no avail. I am tired of the bad service and attitude of these ABSA call centre agents!!! NOW on the 25th of January 2017 they debited an increased amount by R500 without my consent or authorization. I tried calling them but no one is answering their phones and the call centre people keep giving me different numbers that dont work! I am reversing this new UNAUTHORIZED debit order and requesting them to debit the agreed amount without sending my account to collection cause thats what they are good at! I also want a statement of all the money that i have been paying them. </p>
