poor service

<p> I took a contract with telkom mobile /dial direct 6 months ago . I was informed i would receive 5gb data for 2 years ,my data was cut to 1gb after 6 months .I contacted the call centre where a case was logged and i was informed it would take 72 hrs for feed back 3 days later i contacted the call centre because there was no feedback and i was told the case has been closed and resolved i had mention that the issue is still unresolved and how could it be closed .A new case was created and logged . 4 days later when i called again there is still no resolution to the issue , which is now affecting my work as i use my phone for work purposes .I have requested to speak to the manager/supervisor on both occasions but was unsucessfull as they where to busy and would contact me asap. No one to date has contacted me and my issue is still not yet resolved .</p>
