Terrible upgrade service

I requested a upgrade online on 6/10/2020. After numerous follow ups, my order was only given to the couriers on 13/10/2020. They wanted to deliver the parcel on 14/10/2020 but was given the wrong delivery address by vodacom. It is now 15/10/2020 and the couriers refuse to send out my delivery as they have not gotten confirmation from Vodacom which could take up to 24 hours. So it’s been 7 working days since I requested the upgrade and no one is prepared to help and who knows when my parcel will be delivered. To say I am livid and extremely unhappy is a understatement. The service from vodacom has been shocking and they are not doing me any favors, I pay for the service, which is pathetic to say the least!!!
