Incompetant employee

Went to Elgin mall pick n pay to do not alot of shopping however it is their specials that everyone is flocking to them, i got only the basics that was needed for the night, whilst standing in line for 30min, once i reached the till the dimwit at the counter tells me the pinpad is offline. Now why did this tjop not call the manager to assist in the matter but no will stand and wait for every customer to come to the till and tell them that however the person infront of me was able to withdraw money from the till with his card but i rock up the tills pinpad is offline as he stated before he did the transaction. So if it were offline how is it possible for the customer to withdraw money if the pinpad is offline and yet why did he not notify managment to assist? Absolute idiocracy!! So seeing that all the tills are backed up and im not prepared to disomfort others to move back into the shop and move to another lane, i left that trolley there and their staff can now put everything back which i was prepared to buy, but i will no longer support picknpay as their staff is not friendly nor do they have the ability to make a decision to assist properly thus i will take my business rather to somewhere else, lastly i want them to stop sending me messages and emails due to this experience my loyalty to this place is lost
