Absa please can a competent person call me to fix your mistake

Absa I'm still waiting for someone to call me back re. My debit order for my personal loan. I tried for a whole month to get hold of your call centre and when I got through the consultant confirmed my debit or is on system but yet you not deducting. Now you want to hand me over . Please can a competent person call me so that this can be resolved. How can you tell a client you don't know why the debit order deducted . I signed a contract with you and now you not honouring the contract. If I don't get a call today I will just escalate this to the highest person in absa call me *** gf felix
