Disgusting Customer Service Failure!

Edgars Jabulani Mall needs to seriously train their staff members who have attitude for days! on both actual customer services and processes. I have never felt so small upon a visit to the store where a lady who works in Customer services, African, with dreadlocks even offered me the head office number to complain without any worry. I misplaced my card and went to Edgars Maponya sometime in May where I was assisted with temp buying as I explained that I tried replacing the card at Jet stores in Jabulani and was told they are out of stock I need to come back. I went back to Jabulani Jet stores again this weekend 23/06/2018 and was told the same story about cards being out of stock and told I should return during the week - like I have all the time on earth. I enquired about temporary buying and they told me they don't have a process in place and I asked how Edgars Maponya could help me I was told to go to Edgars in Jabulani for help. I then went to Edgars Jabulani where I met the monster who gave me the most horrific customer service I have ever encountered and told me point blank that she wont help me because I am a Jet customer - this left me really puzzled because I thought EDCON is the same group. I asked her nicely how Edgars Maponya was able to help me and she told me she doesn't know I must go back and ask them. I could not hold myself and told her I am going to complain about this inconsistency - her attitude escalated when she printed out the head office number , highlighted it for me and gave me the slip as if saying: "go ahead". This needs to be addressed as I am literally at a point of closing my account as I can never take so much disrespect.
