Extreme inefficiency by pick n pay online clothing department

I've placed an order on the 16th June on the pick n pay online clothing site. I didn't get sent an order number, I didn't get sent an invoice number. Extreme inefficiency! Eventually got through to the online clothing department to locate this order and cancel due to the inefficiency of pick n pay online clothing department. I am still awaiting a refund almost 1 month later. Manager of the online clothing department on numerous occasions has not returned my calls after agents have promised a follow up from him. Extremely inefficient, been given the run around. No accountability! Would not ever recommend the use of pick n pay online clothing site. Dont expect a quick resolution!!!
