Poor poor poor services

My struggle is long with vodacom, I already spoke to all the managers I could ask for but none could help, end April an agent from vodacom called and offered an upgrade Huawei P 40 lite on my contract witch I took, few weeks past didn't get the phone called them after they had already started deducting a phone I hadn't received, I called and was told I wasn't supposed to have been sold that phone to begin with!!!!! That was it and till this month am paying for a phone I dnt have... What are my rights as a consumer?
