Bad cashier service

We were at Ackermans Eastgate and got a bad service, firstly we had to wait 10mins with my pregnant partner to get assisted, that we let slide,

however when we got to the tills we waited another 10mins for the cashier Babalo who seemed confused by what he was doing, he wasn't communicating with us, after 5 mins of him fidgeting with the keyboard, my partner had to ask what is going on until he could tell us his unable to find the code of the item we were purchasing in the system cause the barcode wasn't going through & we asked if he cant get the supervisor or his manager to assist him, he went off and came back again and continued to be busy with the keyboard still not updating us if his getting the code or not,

Just after he walked off again to do whatever he was doing.. A gentleman came through and we asked him to assist us, that's when he advised the cashier to sell the item with another of the same price,, an unnecessary 10min+ ordeal sorted in a minute

It was very unprofessional of that cashier to be busy on the keyboard and walking off without explaining to us what was happening nor asking for assistance from his manager, my partner isn't supposed to be standing for too long at the state she's at, that ruined our shopping experience
