Vodacom consultant

I have been paying for 10GB for 2yrs without have the sim or device from Vodacom. I think it happened the tim i went to do a Sim swap but what i clearly remember is the consultant ddnt gv and asked me about extra Sim Data or any devices Meaning maybe he was just increasing her sales. I have called to trace if i have been paying for someone else bt no even last month data ws nt used even ths month data still the same on this date 06/04 .worse part i have been a loyal customer for more than 20yr using the same number. What im requesting is thy should gv back my money
