Kaak service

I bought a airtime through capitec app last night so just because I owed it paid my debt. This morning I requested R10+R5=R15 then bought a daily combo of 1GB ans 30 min vodacom to vodacom and add 100MB Facebook to my surprise I got 100MB data which is not what I bought. I called vodacom client service to enquire about this. I spoke to a male consultant and explain what happened and he asked me to hold come back to me in 2 min he asked me to explain what I have already explained to him and I did and he said he wants to ask me security questions which I didn't mind he asked when was the last time I bought airtime then I informed him and he said their records doesn't show that I bought airtime so he can't help me. I mean what other vodacom do we have and what he said to me doesn't make sence and I didn't get help and it's not the first time of such happening however I didn't make any follow ups. I feel that vodacom service is kaak
