Worst service ever

I have been shopping from makro for almost two years but today was the worst day of my life as I started approching the till points the cashier didnt even know what she was doing as I was the one helping her showing the barcodes of all the items for her to scan, and i was so patient as I aware of the strike and the were short of staff, I was paying split transation one makro acc the other my own card, they then told me that the speed point is not working. I waited thinking someone will come assist ,then a lady came after 30minutes of waiting not even greetings or apologising for the inconvenience she just took my card an started punching manual without explaining anything using a speedpoint she came with couldn't even say anything as I was ****ed as she wasted my time I took from work and she just left . At about 16:00 while I am busy at work a lady from makro then phoned me saying I owe R501 which they swiped, it surely shows that they dont know what they are doing as I had to explain that they used a separate machine. I have never been frustrated like today still furious and annoyed... from a big brand like makro I always excpect exceptional service ... it was so dissapointing.
