Unauthorized debit order

I am Absa account holder however I consolidated my debts with Capitec Bank. My account was handed over to GVDM lawyers, and I made an agreement with them to deduct R2000pm since April 2015, however on 15 August 2017, was surprised to receive an sms from Capitec Bank notifying me of a deduction of R2305, and GVDM also deducted their amount of R2000 as per our agreement. On 18 August 1017 I went to Caputrc Bank at Jubilee Mall in Hammanskraal to enquire about the unauthorized deduction of R2305. I met with Lindiwe, she communicated with Capitec Bank Head Office and confirmed that my account with them does exist. She later informed me that she cannot assist me because the system does not allow her to make a reversal, but she sent an email to Capitec Vank Head Office to request a reversal, and also advised me to go my bank which is Absa to request a reversal as well. On 26 Auguat 2017, I went to Absa to make a reversal request but I could not be assisted as it qas showing on the system that the reversal was impossible and that Capitec Bank is supposed to do it. On the same date I went back to Capitec and spoke to Lindiwe again and Kelebogile, so Lindiwe called Capitec help desk again but they mentioned that an email was received stating that Naedo transaction must be disputed at the external bank which is Absa. On 29 August 2017 I phone Lindiwe of Capitec again, and she said that statis is still the same but ahe will try to assist and I phoned Lesego Bokaba of Absa of Jubilee Mall in Hammanskraal but she said she would call me befire the end of business day, but she never called and even Lindiwe of Capitec never got back to me. I want my money the amount of R2305 back in my account, and I want an explanation as to why Capitec bank decided to invade my bank account and took money without my knowledge. The two banks are sebding me from pillar to post, I am stuck I don't know what to do anymore, all I want is my money. Capitec Bank should see to it that this matter is resolved because had they not deducted my money I would not be in this situation.
