RCS - Contempo Actrocious Service / *****

I transferred a total of R2800 via EFT to my Contempo account in addition to the debit order that was deducted from my account on a monthly basis. The EFT payments were never deducted from the outstanding amount on my account. The first query that I sent to RCS was on 11 May 2015 in which I included proof from my bank that the transfers to RCS were successful. I sent anther query on 31 July 2015 in which I informed RCS that my account was paid in full considering that I made additional EFT transfers. I did not get any feedback and subsequently spoke to Mambo Kellim on 31 July 2015 call Ref No .(Ref ***). I again did not get feedback until 22 September 2015 when I spoke to Zukiswa Kedama in which I was ensured that the account would be rectified. Again no feedback until 5 January 2016 when I sent another query to Zukiswa Kedama. This query was passed on to Iris Duburooy. The last statement that I received on 13 January 2015 shows an outstanding amount of R3250.31 which substantiates the fact that none of my queries were ever investigated. I haven't purchased anything on my Contempo account since July 2015. How long will RCS Contemp keep on *****ing from me?
