Edgars/Edcon discriminating against foreigners!

In 2015, I tried to change my ID details on my Edcon account, having moved from using my passport to using an ID. That was an issue, with Edcon demanding letters from Home Affairs even after having been provided with all the relevant documentation related to the change. The ID is a government issued document and only because I am not Sout African did they demand an accompanying letter from Home Affairs. As if they have ever received one with any ID from South African customers. I wrote a review on Hellopeter and Edcon responded and the matter was seemingly settled. It turns out they did not change my details. A countless number of phonecalls and going to the Sandton Edgars has not gotten me anywhere. My emails to them have also been ignored. I cannot use the account and yet I have a negative balance. I don't know if this is their way of *****ing my money or what but I am exhausted with this very terrible and despicable service.
