The worst customer experience ever

I went to iStore - Mall of Africa to apply for a contract. I got there October 28th at 15:30. I am told that I might have to wait maximum 45 minutes because they only have one lady working with contracts. So I was like okay that's fine. 45 minutes because 2hours 30minutes. The lady only saw me at 18:00. And yes I sat there inside the store didn't move. After she sees me she starts with the process of my contract application. I gave her my ID, proof of Address, October pay slip and a stamped 3 months bank statement. She does what she needs to online and then the response is I'll have to wait 48 hours. This lady in her words ''I am really sorry this does happen but I promise I'll send through all your documentation to Telkom and I'll call you tomorrow, Monday and Tuesday to update you with the status of your application''. Today is Thursday and she still hasn't called me. On Tuesday I received an email from Telkom saying "My case was closed''. So since the iStore doesn't have a direct line I call Telkom and give them my application number and they tell me that the contract would have been approved but they could not verify banking details because statement was outstanding. So I call ********** 946 and I get through to iStore call center and i explain my situation and the lady proceeds to say she will log a call with the store and said she had sent through an email to the store to be in touch. Again this was Tuesday and i am still waiting. I am so so disappointed because I am a huge fan of the brand but this experience is unsettling.
