Disappointed at Vodacom online empoyee

Today, on the 30th November 2022 I called Vodacom Online as I wanted their Black Friday special on data and voice. It was a R499 x 24 months contract, with 800 mins and 10G. I spoke to several people from Sipho to Lungi and then eventually Vusi. I explained to Vusi that I had an FEB contract and wanted to keep my number and he advised that I cancel my FNB contract immediately and move to prepaid and he will help me port my number back to Vodacom and then sign me up for the new contract. I then called FNB and cancelled my Unlimited Calls contract and then Vusi called me back so we could continue with number porting. Vusi put me on hold for a while and said he was busy sending an e-mail and all will be sorted. The next thing I knew a few minutes later, I was cut off. I thought Vusi will call me back but he never did. I tried calling back but I was on hold for a very long time and never went through to anyone. What upset me is that I was told to cancel my contract and told thst I will be assisted, only for Vusi to just hang up and not call me back.
