Brand fail Poor Service - pillar to post

<p> </p> <p>I have been battling to update my details with Vodacom since January 2017. I have called the call centre no less than 6 times, spending more than an hour on the call with them, to update my credit card expiry date. I have visited 3 Vodashops to update my credit card expiry date. The last time i was told every thing is fine, now i get an sms telling me my account is in arrears. Vodacom, get your act together. you have now convinced me to not renew my contract with you. </p>
