Account badly managed - 3rd HP complaint

I opened an account on 18 February 2017 with this financial provided.

Started purchasing on my account and my first instalment was due on 31 March 2017 of +-R300.00. I made an EFT payment on 1 April 2017 of R500.00. My EFT payment did not reflect on my account (This happens every single month and everytime I am told to use a different reference). I sent my proof of payment and it took weeks to allocate my payment.

I paid my instalment as follows: 1 April 2017 - R500.00 28 April 2017 - R650.00 1 June 2017 R661.01 1 July 2017 R760 30 July 2017 R760

Somehow these stupid people keep telling me my account is in arrears by over R1000.00 after sending numerous proof of payments and numerous calls despite the fact that I am overpaying my account every single month. Why the hell do we need to deal with this incompetence??? You guys are badly affecting my credit record by not managing my account properly!!!!

How many more ****ing calls do I need to make, emails do I need to send, Hellopeter complaints do I need to log for these people to do their ****ing job.

Get this ****ing **** sorted out cause I am sick and tired of dealing with an *********** company (RCS) and would like to pay this account up and close it.
