Blocked on Vodacom customer care due to a complaint I have

I have made an upgrade towards my Vodacom account and I received a notification form skynet via sms that my package is on the way, no phone call or anything, the package never arrived at my place, According to the details on the waybill it was a bad address, I made numerous calls to Vodacom customer care and Vodacom online regarding the incorrect address and that the delivery never came, they blocked me on all the customer care numbers so I can't contact them, this is extremely pathetic as I have supp**** and spelled my address more or less 10 times over the phone while making the upgrade, I went into Vodacom and the assistant said she won't be able to assist me with the online upgrade done, so next month i will probably receive a bill for something I did not receive and the service is pathetic as no one wants to solve my problem,
