Payment error

I went to Edgars store at Mall of the South, they had system issues to process my purchase, so I could not buy the goods after multiple attempts by the teller, but later got 2 sms's stating the purchase did go through, so went through twice. Called the call centre and was advised to send an email to Payments, only to be told by payments via email to go to a nearest branch to go raise the issue. Pathetic
