Poor service at Shoprite Blue Downs & lack of cleanliness

Terrible customer service at Shoprite Blue Downs centre. Came to do my groceries a month ago and a cashier made an error resulting in me paying R500 extra. Raised this with the staff members and supervisor and it took them over 1 hour to resolve until I called the manager. Not satisfied with the outcome as the manager still hasn’t not contacted me as promised regarding the matter. In addition, this branch lacks cleanliness and generally has bad customer service with very long queues.
