System error but just reapply.

Been waiting to upgrade been receiving sms's and notifications from MTN to upgrade and the phone i want was out of stock so i waited. All of a sudden on the 9th November i receive a call to say they have stock and we can upgrade. Do everything and the lady says DSV will be in touch. DSV calls and books the delivery for Saturday 11th November 2023 and ask for me to make myself available for them to deliver. 1 Pm comes and nothing. DSV call centre closed. Called on Monday the 13th only for DSV to say the parcel was sent back at the request of MTN. Call MTN go through what felt like 5 different people only to be told that i need to reapply for my upgrade as it was cancelled and they cannot tell me why. Why should i reapply when they have everything and it was cancelled on their side because there was a problem with DSV??? Makes absolutely no sense, gets left with me to call and find out whats happening and just more inconvenience for me?? Absolutely flabbergasted at how they arrange everything and have you waiting on the edge of your seat but then just dont deliver..... Literally!
