On 10/03 Thandeka (sales) run with application for explora pricelock special which was approved. Arranged for adhoc on 18/03. Nothing went off. Week 22-24/03 Nkololeko (CS) to FU. When I call him he cuts of my calls. When I called in I was requested to send proof documents. Sent on 28/03 REF ***. Received email stating that documents couldn't be linked to existing customer act *** and escalation was sent to sales team to recapture application. Spoke to Neo Motautona (CS)on 05/04 and gave feedback 08/04 stating that I need to forward all documents again to cred dpt. Sent docs again REF ***. Spoke to supervisor Prince Nqakwana on 08/04 demanding that this mess to be sorted out. He promised that he will log complain and call back on 11/04 which he did asking if anybody has called met yet. I told him that I received no calls and no feedback. He promised that he will get someone to call me that day still -nothing happened. On 12/04 I spoke to Abraham (CS) REF I247954. He said there is no movement on my acct and sent email to Prince requesting him to give me a call. Today is 13/04 and still nobody called, no adhoc payment went through and nothing was delivered.
