10 days and incorrect contract allocation STILL not resolved

I renewed my contract online and the upgrade was then allocated to the incorrect number ( i have 2 numbers with Vodacom). Received the device after a week AFTER i phoned ********** 4 several times trying to cancel the incorrect allocation. That number just tells you to stay on the line for the next available operator. Posted on Twitter and got promises that issue will be resolved. Eventually got through on one of their other 082 numbers. Vodacom collected the incorrect phone (which they said will enable them to reverse the incorrect contract allocation) on 14 dec 2017. NO word from Vodacom since then. I DM'd them again via Twitter. No response other than they're waiting for the phone to arrive at their warehouse after which they will reverse the upgrade. It's been a week since you collected the phone! Well, today STILL no word from Vodacom other than SMS's i receive stating query has been logged and i receive reference numbers of new queries (which they must've logged). AND then i receive SMS's stating queries has been closed. Why close if it has NOT been resolved. So Vodacom is closing their own queries!

So, still unable to upgrade my phone and Vodacom loaded the new INCORRECT contract and invoiced me!
