MTN poor service

I ordered a cellphone online on the 21st May 2024 up to date I have not received my order I called the DSV to check on my order since it was said that it will take 3-5 working days to get my order the lady that I spoke to told me that they have been trying to call me to arrange for delivery but they couldn't get hold of me I asked her on which number did they try to call me on she called out the wrong number I told her that is not my correct number she then said I should call MTN direct to change the number I have been trying to call but am not getting any help because I keep on being transferred from one consultant to another. I even tried getting that order canceled so that I buy from other service providers they told me I can't cancel because it's an open order I don't even know what that means.
