no network on SA's bigest network

<p>I have a Telkom Mobile Mobile Data contract. lately I can only get a poor connection at home. when going to JHB centre or Midrand I get no connection. I land up buying data from other service providers to get a decent connection. Data connection used to be OK at home when I first got Telkom Mobile, but no longer. I get told to change to Roaming and disable roaming back and forth but still a poor connection. I would like my contract cancelled.</p>
