pathetic service

On Tuesday 16 June 2015 I was at the Game store in Century City & received bad service from the cashier Miss Ncebakazi. I was there to make payment of full outstanding balance on my account. I was assisted by Ncebakazi & behind her another lady also that works for Game. I told the cashier I would like to make the full payment of R1,358.00 and I handed her the money of R1,400.She then requested my Game card & asked me again if I'm paying instalment of R200 & sumthing after i told her I'm paying full amount of R1.358 she asked the lady who stood behind her to void & she took slip &left , during whole sale she was chatting to her colleague @ the till next to her.she then for the 2nd time asked me my card to swipe & once again I told her im making a payment of R1.358 to square up account she then tilled payment up again while talking to colleague and gave me a till slip so i checked my slip she gave me & she only tilled up R1,300 & another mistake i told her 3rd time it's wrong why is there a balance? She took card & tilled up eventually R1,358. i walked away & asked the gentlemen that works for Game to call a supervisor who came & said she will speak to Admin.Unprofessional!
