Bad customer service with opening account

I am being sent from pillar to post to simply follow up on my account.

The first instance is the call center lying to me and telling me that they will call back in 15 minutes from the store. I emailed and was told for urgent inquiries I should use Edcon number. This number also refers to me to a call center that wants me to go to the center again. The claim is that they cannot verify if it is me. The supervisors were apparently on training and could not escalate this matter. I asked for an email and was told that there is none. I settled for a number given at the last center only for it to be hung-up on me while I am going through the voice prompts.

I need verification before I travel again and look for alternatives.
