Pick n Pay online shopping sucks

My sister lives in England and she placed an order with pick n pay online shopping about a month or two ago for me. On the day the order was supposed to be delivered I noticed a mistake in our address so I phoned them to rectify it. I spent all my airtime and was given quite the runaround to fix everything. My sister then placed another order for me and yet again there was a problem. My sister sent all the correspondence from pick n pay and one of the emails was to say the order was successfully placed and on the day it was supposed to be delivered they sent my sister an email to verify her bank details this after a successful delivery a month or two ago. Again I used up all my airtime trying to rectify the problem but was again given the runaround and my order was not delivered as per email. Delivery date was 15th of April 2019 between 14h00 and 15h00. Order number # ********** 0134
