POOR SERVICE WITH UPGRADE AND RAM COURIERS

I upgraded two of my contracts. Received an email from RAM that they cannot contact me as my contact number and address given by Vodacom was incorrect. One of the parcels found it's way to me when I confirmed my details (the invoice given by Vodacom had completely incorrect details, not even a previous address or phone number). RAM advised one parcel was returned to Vodacom due to incorrect details. I phoned Vodacom and was asked how I received one parcel and one was returned (really? I'm the courier now?), and that I must phone again on Friday because they have not yet received the parcel back, they cannot do anything for me. It was a Vodacom consultant's mistake, why can this not be corrected and why was incorrect details given in the first place??
