None Delivery of an MTN Upgrade Parcel

I have been an MTN loyal customer on Prepaid I do not know for how long and +-24 months on Contracts(2 Contracts). On the one contract is the Data sim which I Upgraded a months or two ago with no Issue. The other was an Iphone 8 due for an Upgrade which I decided to do online and go for a P30 lite. I completed everything online including Delivery Address. The site even showed Primary account holder number. A week later I call MTN to the track I was told to call DSV who is supposedly the ones who will courier my package. DSV Tells me my Package is being prepared for delivery and I will be contact to organize Delivery. I never got that Call. Today I call DSV again to check on my Parcel. I'm told delivery is halted as I could not be reached. I do not recall missing any calls from MTN or DSV. MTN has my three numbers that I have with them but are telling me I could not be reached in all 3 numbers?? DSV instructs I call MTN I call MTN and I'm being sent to different department which eventually some guy says I must call *** which tells me they'll charge me R2 for a minute in the beginning??

If you do not wish for me to be an MTN customer anymore kindly advice to which network you wish that I port to which will do a far better Job than you guys are.
