Wesbank not responding to correct e-mails

Last year May 2018, I bought a Kia Picanto 2018 model, and this year January 2019, we sold our current property, so that we can move to a bigger house and is in the process of buying this property. As a loyal client of Wesbank, I informed the Bank that my address has changed, I could have kept quiet like a lot of consumers is doing, on 19 February 2019, Wesbank informed me that the documentation that I have forwarded to them is not correct, I went to my lawyer on 19 March 2019, and she Commissioner of Oath our Lease agreement until the property is registered as we are busy with sub-division of the property, and I attached my Credit Card to show my new address aswell, Wesbank says that you will receive a response within 72 hours, yesterday I did a follow-up as I need to resolve the matter regarding my address, I have re-sent the email of 19 March 2019, two times more now, and everytime the consultant keeps on referring back to the email of 19 February 2019, I am talking about the email of 19 March 2019, but it seems to me people doesn't understand and is *********** of doing their work. My car gets deducted from my bankaccount via debitorder, but it seems to me if you are a loyal client, you don't get any clients service afterwards.

I can see that the emails is being read all the time and opened, but no response.
