Prestige client standard bank almost 2 weeks and still no answer

I honestly can't believe the experience I have an with a so called private banker. I wanted to move my Absa vehicle financing to Standard bank since the 10.11.2025. Each day I send what is required from Lusanda Ningi then I get told I will get feedback the same day but nothing. Then when I follow up the next day then only she replies and asking for more outstanding documents. If I don't follow with her I don't hear from her. On the 14th I decided to email the 2nd escalation which is stated on Lusandas email Sherezaan ****er which I got no reply from I then emailed Sherezaan the Monday 17th again and still no reply. When I call I get through to the call center cos apparently they can't get calls. Today is the 19th and I still don't have an answer. I would like to change this private banker cos this is by far the worst experience ever being a prestige client.
