Poor service!

I bought 2 items on 1 order and on 14 Feb 2023 I went to collect the order at Richmond Park Pickup Point. At the counter I opened the box only to find 1 item inside. They then submitted it and then said I will receive a notification email to collect the outstanding item. By Sunday 19 Feb 2023 I drove to the pickup point to speak to someone directly to assist me, it turned out that someone along the line never followed up. I then gave my business card to the person who assisted me on 14 Feb 2023 as well and I asked for her to please phone me the next day, Monday 20 Feb 2023. It is now Tuesday 21 Feb 2023 and i have not received an sms, email or a call with regards to the outstanding item that I have paid for. It is unacceptable!!
