Upgrade without my consent

On the 16th of September 2024 round about 14h18 I have received a call from one of vodacom consultant asking me if I was aware of my contract coming to an end on the 29th of November2024 and I told him that I was aware then he asked me if I was going to upgrade I told him that I'm not going to upgrade and he said it's okay but since I have been a loyal vodacom customer vodacom is going to give me a speaker for being a loyal vodacom customer for more than 12 years then he asked me to give him my address where they going to deliver the speaker that vodacom is giving me for free so I gave him my address where the speaker will be delivered because I was in the hospital where me and my kids where admitted I told myself that once they discharge me I am going to vodacom where I took my phone contract with to ask if this speaker thing is true then the lady who was helping me she checked the system and told me that there is nothing on his system it only showing that my contract is ending on the 29th of November2024 and she also said the are vodacom agent from another company who have been doing this **** upgrading clients contracts without their consent and she advised me to call vodacom I did that I have been calling vodacom customer care and they are taking me from pillar to post yesterday I called vodacom again and the gentleman told me that they are escalating the matter I should give them 24 to 72 hours. This morning I have received an upgrade message I have lost faith in vodacom and I don't want anything to do with vodacom
