Lack or training, customer service and False advertising.

I visited your Greenstone store on the 13th February 2019, I was looking at making a high value purchase and required a credit limit increase. I completed the documents and handed over the documents required. I then left the store, later on that day I was contacted by Lawrence who advised I app**** for the wrong product and should apply for the Credit Top Up, I had to go back to the store to change the application. ( Clearly training needed) . On the 14th February 2019 I received an sms stating the app was declined as I have not submitted supporting documents. Baffled and confused because I was in the branch when the documents was submitted I called the call centre only to be told I have to go back to the branch and resubmit. I few min later I received a call from Lawrence advising that the sms was an error and they do have my documents, he then asked me to send another copy of the back of my id card. ( training issue, branches should be trained on what is required).I submitted this . On the 15th February 2019 I received an SMS confirming my application was approved. No call to explain how this works, I then called the call centre and got the info I needed. On Saturday the 16th February 2019 I called the call centre to inquired if I could change the purchase store and was advised I could. We made our way to the Mall of Africa where Goodness assisted us. We chose the item however when we needed to process the sale , there was absolute confusion on how the Top Up credit worked ( Training issue) , She did her best to help us but we had to leave as the store needed to close and there was no manager, regional manager or no one at the call centre could help. On the 17th February 2019 I called the call centre and spoke to Edwina ( very help full) , she explained that there is no issue and I could go back to the store to process the sale. I went back but once again total confusion. Goodness called the call centre and spoke to Thembi who was extremely rude and did not want to listen, Eventually Thembi put down the phone on Goodness( horrible experience I am witness to this). 2 hours later I was now extremely frustrated and unhappy I called the call centre and spoke to Edwina. After a while she then assisted Goodness and the sale was completed. However this entire experience is shocking. I asked for Zelda's the regional managers number and was told I am not allowed to get it. What further frustrates me is that apart from this sale we made a purchase on Saturday . When I asked why were we not given the charms as advertised we were told it is subject to availability and there was no stock. However nowhere on the adverts did this say so. (False advertising). If I was not in a hurry to make this purchase I surely would not have purchased from American Swiss. Serious lack of disciplines and training across 2 different branches and the call centre. I would like a call from a senior manager urgently.
