plain pathetic customer service

i have continually complained about this particular branch to the pick n pay hotline. however the service never improves. pick n pay's promise is that there will never be queues in their store unless all their tillpoints are open. that is a lie by this branch. i was there saturday and there was only two tills open with long queues. when i asked the supervisor about it she just ignored me. this is not a once off occurence. it happens very regularly. i have come to the conclusion that the store manager is to blame as he doesnt check up on these things. i have spoken to him over the phone about my concerns but there is no improvements at all. the staff have no good ways of dealing with customers.
