MTN CONTRACT UPGRADE PROCESS SUCKS!!!!!!!!!!!!!!!!!!!!!

I AM CURRENTLY EXPERIENCING THE WORST CONTRACT UPGRADE EXPERIENCE I HAVE EVER HAD IN ALL MY YEARS OF HAVING CONTRACTS WITH DIFFERENT NETWORK PROVIDERS. I CANNOT BEGIN TO EXPLAIN HOW UNPROFESSIONAL AND INCONSIDERATE THIS PROCESS HAS BEEN. I INITIATED A CONTRACT UPGRADE A WEEK AGO ON 03/09/2018, I CALLED IN THE NEXT DAY TO MTN FOR AN ETA AND TO ENSURE THEY HAD THE CORRECT CONTACT DETAILS FOR THE COURIER COMPANY, ONLY TO BE TOLD THEY CANT PICK ANYTHING UP, BUT GAVE ME THE COURIER COMPANY CONTACT NUMBER AND A TRACKING NUMBER. I PROCEEDED TO CONTACT THE COURIER AND THEY WERE ALSO UNABLE TO PICK ANYTHING UP AS THE PARCEL HAD NOT YET ARRIVED IN CAPE TOWN. THE PARCEL HAD EVENTUALLY ARRIVED IN CAPE TOWN ( I CALLED EVERYDAY) BY TUESDAY 09/10/2018, I HAD TO CALL THEM TO SCHEDULE A DELIVERY TIME. THIS WAS SCHEDULED FOR TODAY, 10/10/2018 BETWEEN 9AM AND 1PM. IT IS NOW 2PM AND I HAVE NOT HEARD ANYTHING. I HAVE TRIED CHASING IT WITH DSV, THEY CANT HELP ME, THEY WILL CALL ME BACK, THEY DONT CALL BACK. THEY PUT ME THROUGH TO CAPE TOWN BRANCH, BUT THEY OPERATOR SAYS I'M STILL IN GAUTENG. I GET THE DIRECT LINE FOR CAPE TOWN, THERE IS NO ANSWER. I CALL THROUGH TO MTN, GET SHOVED AGAIN FROM PILLAR TO POST, NOBODY CAN ASSIST. I GET THROUGH TO GENTLEMAN, I GIVE HIM MY PLEA AND ASK PLEASE TO BE ASSISTED AND NOT TRANSFERRED, HE PROCEEDS TO EXPLAIN TO ME THAT I NEED TO CHECK WITH THE COURIER COMPANY WHICH I JUST EXPLAINED TO HIM I HAVE BEEN DOING FOR THE PASSED WEEK. I ASK HIM TO TRANSFER ME TO HIS MANAGER AND HE TRANSFERS ME TO AN OPERATOR WHO SAYS THE NUMBER I HAVE DIALED IS INCORRECT, PLEASE TRY AGAIN. I AM NOW LOST, NO PROGRESS. I WOULD JUST LIKE TO CANCEL EVERYTHING AT THIS POINT!!!!
