Faulty tills no assistance from managers they cold heated.

Go buy my groceries at overport checkers, get to the till they ring up the groceries then the cashier presses something wrong the till freezers then the manager Melody assists her and switches something on the till they make us wait for over half an hour we request to be moved to another till and let the groceries to be rung up again melody refuses and says we have to wait for the till to upload again so we wait then I request for cash back and swipe as she tells me to.. The slip don't come out on their side but my app states I have paid I'm with my 8month old baby waiting for this transaction to go through I'm exhausted and my baby is tired and hungry. Then once the slip don't reflect on her side they decline me of my groceries or even trying to help me in anyway because the fault is on their side.. The other manager Leon comes and tells us we cannot take the groceries so we leave with no food or money.. To be told the next day when I called by Melody that it reflected in headpffice so I ask her please assist me because I need the food I'm working she says they cannot assist me I must come fetch the money and sign I asked if they could shop for me and deliver the same items because I cannot come due to me working Monday to Friday she refused to assist me in anyway possible regarding the groceries and apologized for the inconvenience cause on their side due to their faulty till. Now this is heartbreaking and pathetic service being provided because checkers was at fault not me or my bank... I'm without groceries because of them now I must wait.
