Clicks online

I ordered from clicks 25 April 2020. The parcel was delivered to my nearest clicks 30 April but there was a pack of nappies missing. I contacted the customer care directly from my clicks store and was assured that I will receive it within 42 hours and even given a reference number. When I phoned 7 May to enquire as it had been 4 working days already and a weekend, I was told the lady lodged the complaint wrongly and that a new consultant will call me back the same day or next day confirm a new time of delivery. I didn't receive the call. I then resorted to posting on clicks Facebook page and after that a third consultant phoned me on 11 May and also said he would call me back to give me more information and try resolve the issue. It is now 15 May and I still have not received any feedback or my missing pack of nappies or any indication of when it will arrive. Very disappointed as I have been ordering from Clicks for years.
