No feedback on monthly instalment

<p>I have been querying my account since November 2016 and have not received any feedback yet!</p> <p> </p> <p>I have an amount outstanding due and payable over 36months so I do not expect the instalment amount to be high. Yet every month my instalment amount changes? How am I to budget myself?????????/</p> <p> </p> <p>Stupid people working at the call centres who beat around the bush and tell you everything else except answering your question. RCS REMEMBER THE CONSUMER HAS RIGHTS TOO!!!</p> <p> </p> <p>I sent a second email last week and to date have no feedback. It is either you people are *********** to do your job or just blatant to customer service.</p> <p> </p> <p>Really pathetic for such a big company</p>
