Vodacom has the worse service

It completely blows my mind how bad the service is at Vodacom. I've upgraded my contract on the 29th December 2022 and up until today have not received any new device. I call and being transfered from pillar to post without any assistance. Now finally I have had it with them and I should hear that I can't cancel my current contract because its in arrears and I've being paying religiously every month. How am I able to receive the benefits of the contract if I've been in arrears all the time. I would really like someone from Vodacom to contact because I don't get straight answers from the call centre and had to deal with rude team leaders.
