No response: Private Vehicle Finance consultant

I have app**** for Private Vehicle Finance online through FNB/Wesbank on 13 March 2015 for a 2013 Geely LC. I was approved via the online application pending document verification. I sent my documents to them on 16 March 2015 and received no response. I contacted them ***) on 17, 18 and 20 March to find out the status of my application and was told that my application was approved and that a marketer/consultant would contact me later that day or the following day. The last call centre agent I spoke to (Tebogo) tried to connect me to the marketer so that he could explain the installments and the deal to me but he was apparently busy at the time. She sent him an agent request but he is yet to contact me. The car I app**** for was eventually sold because the bank took too long, I lost another car as well due to this problem. This is very frustrating and disappointing, it makes it seem as it they do not want my business. I am an FNB customer so I decided to apply through them, however I get such poor service.
