Faulty Vodacom sim cards

About a week ago I realized that my whatsapp messages is not going through, but i got a few calls during the day. So, I called Vodacom to ask them just to have a look to find out what the problem could be, little did i know that this is where all my problems started. So in short i ported my number from Cell C to Vodacom due to network being better. So after about 4 or so sim swops and spending countless hours on the phone asking Vodacom what is wrong with the sim cards they are selling they just keep on tell me, well it is showing that the sim swap went through on our side, which is a lie because it is not working on my side. So people DO NOT BUY VODACOM SIM CARDS, 90% of them is faulty and VODACOM IS LYING TO YOU
