Very bad customer service

<p>Bought my son one of those vodacom tablets on Friday the 21/04/2017 it was working just fine until yesterday the 23/04/2017 when his dad tried to call him with his MTN cellphone it did not go through. So I tried with my vodacom phone to which it went through. I then tried with my sisters and the helper's number as they are also on MTN to which in still went on Voicemail. I called the customer service centre to which they advised i must switch it on and off , reset the network operator to which i did and it still did not help.</p> <p>I then called them again to say my son still cannot receive calls from other networks, to which they advised I should visit a vodacom shop for further assistance . This morning went to vodacom and they also could not assist. They even went as far as putting the sim on a different phone and it still did not receive calls from other networks. The manager had the nerve to tell the consultant tell me to speak to the call centre again instead of trying to find other ways to assist . I have been going back and fourth with this and Vodacom has shown no interest in assisting with resolving this as the problem is with the sim card not the phone. This is really pethatic.</p>
