Online shopping nightmare and no one to turn to when there's promises broken

I bought and paid for a baby travel system online on 29 Nov 2019. Delivery time was supposed to be 5-10 working days. When I never heard back from them I emailed customer care and was told by Ayanda Ngidi that my parcel was with Dawn Wing couriers and I will be getting it soon. I noticed that they captured the postal address for my parcel wrong because I'm in Durban and they have a Cape Town Township address. I phoned Toys R us customer care and Dawn Wing a few times to make sure they don't deliver my parcel to the wrong person. Toys R us promised me I will have my parcel by 17 Dec 2019. That day came and went and still I'm left waiting. I've tried phoning customer care at Toys R us and Dawn Wing a few times today but no one believes in answering their phones. The tracking number that was given shows the parcel was delivered to Cape Town. I've had no communication from either company contacting me telling me where my parcel is that I've paid for. Just empty promises! I'm beginning to feel like I was ****med out of my money for goods paid for and delivery charges and Im left empty handed 3 wks down the line. I'm 9 months pregnant and my baby is due in a few days but I've had to deal with all the unnecessary stress and extra telephone/data costs and the companies mentioned are not contacting me to sort out the problem.
