Vodacom

I missed a payment on my wifes vodacom contract but i paid it before the month ended. She did not receive her allocated airtime. When we called in this evening 28/03/2018 they gave us same bull**** story they give everyone else..... There was an internet session and calls was made. The lady gave us the date the calls was made and we checked it on my wifes phone during the call. There was two calls. In call lasted 12sec and the other was 17sec. So basically they telling me i paid a whole month to only speak for a half min and ontop of that her phone was barred by vodacom so she had to use wifi hotspots. This is not the first nor the second neither the third or fourth time this is happening. I feel bul**** in paying for a service that we dont benefit from. Also the airtime or data one gets as a topup customer disapears much quicker than on prepaid
