Refuse to refund an ******* deduction

Good day,I would like to lodge a serious irregularity that occurred within your organization and would appreciate an immediate refund on my account<br> <br> In October I contacted your collections department to inform them that after 2 years I have finally found work again and that I will be paying my full instalment of R4033 and I was asked if I could not pay an additional amount of R500.00/month to minimize the arrears to which I agreed for 3 months,Nov, Dec and Jan,which I adhered to<br> There were two occasions where I had to be refunded for the arrangement being broken and double deductions went through,one being Ref no *** <br> I then spoke to Phidile on the 24th and she asked if I could not lift the additional amount and I agreed to R800 above the R4033 for end of Feb,Mar and April Arrangement *** and ***.<br> <br> Without my consent and without any notice this arrangement has been violated by a deduction of R21 000 from my account,this has left me in terrible financial disarray and I am facing law suits if I cannot pay my accounts on time,I have offered to pay back the instalment as well as an additional R800 per month
