Poor service delivery

Since I placed an order on the 14/12/24, I haven't received to date, apparently the courier couldn't reach me because they had my old number, I phoned Bash customer care centre and explained the story, I was told that the courier people will be sent my new number and the parcel will be delivered in no time. I waited then I heard nothing from them(the courier people) then on Monday,23 December 2024 I called again, then I spoke to the lady called Siphokazi, I don't wanna lie, the lady was so rude, she insinuated that it was all my fault because I am the one who gave them the number, they did not give it to me, I tried to explain I have updated my profile which means they know that I no longer use the old number that courier people are using but she was somehow admant I am at fault, to be honest I am not happy with how everything has unfolded, I think as a customer I need to be treated with respect. I am wondering if the parcel will arrive on 27/12/24 as they have promised because they keep postponing.
