TFG does not honour my needs asked for

So about a year ago I called in myself to customer care to ask them to remove all benefits from my account on request. The lady that logged it assured me this will be effective as per the new month. Till today I am still receiving all the benefits and calls for insurance, funeral cover and all other benefits that Iv already requested to cancel. This is a new year and I am tired of calling in our my own account asking TFG to cancel something I have long requested for. The other thing is I also requested about four months ago that my account be blocked so that I can just pay the account off without using the credit. January 2016 I come to learn that this was reversed back to what it previously was without my consent . I am so sick of TFG and they never action my requests and I am a loyal payer but I am sick and tired of this now. A whole year of paying extra whilst I should not have been paying extra because of TFG's mistake. I need some assistance on this matter please.
