Poor service from atlas branch and their call center debt tech

Hi my name is nandipha,in the month of february 2021 I app**** for a loan at the above mentioned financial services, I was given an amount of 4000 which in return I hd to pay 6300 in 3 months installments of R2100.i paid 1st installment end february beginning of march I received an offer of a 75% discount for my long term long term loan which I was struggling to pay for years,I took the offer but now I had to change bank details so I can be able to settle this loan month end of march ,in April month I went back to atlas in kuilsriver branch to update my new bank details so I could carry on with my payments I requested the lady that was assisting me to do the debit order of 1000 the same day she then told me their system had issues so she will do it for the following day but the money wasnt deducted stil, I then used the money. I went back in may month to pay 2700 cash I refused a debit order due to the fact tht it failed the PREV month,so I was afraid that I myt use the money again if they dont deduct,thts where the problem started the guy who was helping me there was very rude when I wanted clarity on the amount that I was paying ,so he separated the 2700 told me that they have staten issues so he will have to separate the money, 2100 was paid and 600 paid separately he gave me 1 proof of payment of 2109 and he asked if he could email me the other proof of payment for 600,that was weird however I agreed I never received that email ,in june I had financial issues and july so I got my salary in August when I went to settle remaining balance of 1500 I was told they handed over the loan to debt tech they gave me their details same time I called to make the payment arrangements to pay ,to by surprised the amount has increased to 2100 ,I asked the reason why the amount is that high the lady who was attending the call told m ts due to the call I have been receiving, I told her that's a lie because I have never received a call from atlas I was communicating with that rude guy and I stopped communicating with him due to his rudeness, I then payed that required amount of 2100 because wth those crazy charges this payment was done 25th of aug 2021 after 30 days I find out that my name was not updated at transunion I phoned debt tech same lady was assisting me she told me t takes 30 days to 60 for my name to be updated I waited another month I check again on the 26 Oct 2021 still it was not updated until now, yesterday and today I phoned operative manager told me they've done their part they can't help me she doesn't know what to advise me cause the account is back I asked where she says at head office service is so poor when I called yesterday the other lady made fun of my situation she speaks her language (zulu) I heard what they were saying they laughed I don't know what to do
