Mobile Talk leads to no talk

<p>I've signed up for a 20 GB contract with Mobile talk on 18 March 2016. They've convinced me to cancel my Telkom ADSL and replace the service with an LTE from Mobile Talk. They've never given me the service for 20 GB but only signed me up for an 10 GB contract. I haven't received a contract with the LTE nor are they sending me an invoice on a montly basis. I've raised complaint with Mobile Talk and Telkom-Centurion Mall on Thursday 26 May 2016 without any success. My bank account was debited just now with exactly the same amount as the previous months which means that I'm still on 10GB and not on 20GB as the contract was sold to me.</p>
