Completely disgusted by the service received from pick n pay asap I orders on the 27th of Feb 2022 I received my goods but was overcharged on my meat items and discovered items missing I contacted the call centre immediately and wS advised to email pictures I did that..I called on Tuesday and another agent advised their emails aren't working... hh provided his direct email ad I emailed again still no response I called back a few days later and was completely irate as I haven't recieved any feedback the agent that assisted told me to email her again an she will send me test email ii hint even received a test Email for days,only when I posted on Facebook I received feedback saying an agent will call me ,no one called up to date.then on the 12th o March I received an email stating refundd process d will take 3 to 7 working days. I waited expecting a refund still nothing. I posted again on Facebook on the 24th March and was told refund only processe on the 21st March and must wait 10 days and guess wat today's the 1st o April and still noo refund...I will never use pick n pay again I'm appalled by te way I'm being treated for my own money back
