New account *****? Bad customer service!

I app**** for an Edgars account at Sandton City yesterday with a gentleman named Trevor. I was told that on approval I would receive either a call or an sms. At 5pm I received a call from Trevor saying that the acc had been approved and I needed to come with my ID. On arrival at the New Accounts dept I was assisted by Nolitha who explained to me that the acc I was approved for was a JET acc & that I needed to go to JET to collect it. I explained countless times that I opened the acc at Edgars & wanted my acc at Edgars specifically! I even opened it for the vouchers I would receive at Edgars where I do shop and not JET. I asked for assistance from the store manager at Sandton City and without even acknowledging me, she dismissed the issue entirely saying she couldnt assist me as new accounts was closed. I called Edgars again this morning and they said Trevor shouldve told me that JET invited me to open the account hence why I can't open at Edgars - what invite they refer to is beyond me! I then called the call centre and was told that there is nothing on the system with JET & no approvals happened! To me, it sounds like an acc was opened *****ently at this stage! Help me understand
