Pick n Pay horrible customer service

Ordered online not knowing the shop was closed, they accepted my order and stated delivery will be done the following day ( order placed 18:30 ). There is no option to cancel your order, no department to call as they were also closed and online purchases could not help. I did a conplaint on their app trying to cancel the order and get someone to call me bit contact was made almost 2 weeks later. The email received was that my ticket has been closed because "many" customers has already been assisted. The assumption that one was me. Afterwards I receive the email giving me an option to rate the service except the ticket was closed by pick n pay so I could not give a bad review.

This is 2 days after Pick n Pay Sunninghill shut off the lights of the shop while myself and numerous other customers was still in the shop because it was 15mins before the actual closing time
