Only 2 tills open

I'm writing this complaint with the utmost disappointment. I visited Pick n Pay Hemmingways mall on Thursday the 29/10/2020 and it was about 15:00 in the afternoon. I purchased some items and went to queue at the tills but as usual no matter what date or what day it is, there is always just two till open. Normally we just stand and wait our turn but that day we stood and stood and the lines were not moving, both tills were stuck because they were attending to those customers who had problems with the advertised prices of items they had purchased, so I went to the supervisor and asked her if there was any way they could open another till to help the other customers and so she said to me just go to the info desk to pay because we busy with something over here. So I went over to the info desk, when I got to the cashier, she started to complain and moan that i had more than 5 items in my trolley. I told her that the supervisor sent me here but she goes on and so i asked her now are you blaming me for these long queues and she said no but she still complaining. I left the store so ****ed off and fuming because this happens so regularly and if someone says something then the staff give the customers attitude. This needs to dealt with because its pathetic behavior.
