False payment agreement.

I made an payment arrangement with Ts legal services to pay R200 on a loan account. Every month I make my payment and end of August 2018 I made my payment then I got sms's and emails that I didn't and after calling I was told that they changed to a new system and I should send an proof of payment so I sent it and payment was allocated. After all that I received again sms's telling me I did not pay so I called again Ts legal services and they alologised because the robot is programmed to do it. After a few days again I got an email stating a Final demand letter for the loan amount again I called and was aplogised and will look into the matter, Monday I received an sms telling me I should pay R443 again I called and asked what the hell and the lady said she will look into it and will call me back, I never got my ****ing phone call!! Now I received a ****ing email telling me I made an payment arrangement of R443 to pay which I did not because I can't afford it. Where the hell is the ****** proof!! Hope Selaledi you should get your **** together, everytime I tried to call Hope Saleledi then I can't get throught, this is getting rediculous, first t you don't accept my agreement throught dept counseling and now you ****ing me off by changing my innitial arrangement of R200 every month. I did not agree to anything regarding the R443 payment agreement that was sent to me via email. I demand an apology letter, I demand a statement where my August 2018 payment was allocated and I demand a senior management calling me regarding my account because the people I'm dealing with is ***********.
