My complaint still not resolved by vodacom

I lodged a complaint with vodacom about 2-3 weeks ago. My complaint was about a new contract phone I took, I specifically told the sales consultant that I don't need a new vodacom number as I am already a vodacom customer. When the phone arrived at home, it included a new vodacom SIM card. I complained that I don't want a new number like I stated in the beginning. A consultant from complaints division called me and vodacom arranged for the device to be picked up so that a cancellation of the contract be initiated and they said they will call me for a new contract where they will use my existing vodacom number.

Ram picked up the device on the 05th March 2019, since then I haven't received a call from vodacom to acknowledge the receipt of the device. The Ram ref number is COL ********** 3.

For how long must I wait to be assisted with a new phone? Or should I just forget and go to another service provider.
