TELKOM ADSL Service Unacceptable

Since upgrading my Telkom ADSL line about (4 weeks ago) to uncapped @ 4Mbps I have have logged 4 fault reports and phoned Telkom several times to complain about my ADSL line speed. According to competitors I should be achieving at least 3,6Mbps on a 4 Mbps line, my line speed however is between 260kbps - 360kbps.<br> <br> At this speed my DSTV connector box is unable to download and browsing the internet is completely impossible. My most recent fault report number is 6CRK211015 with escalation number #767853. I received an sms yesterday informing me that the problem has been resolved, but my line speed is still at 320kbps!!!<br> <br> I am so frustrated and have indicated my intention to switch to a competitors ADSL package. I have also informed TELKOM that I will not pay for the upgraded services because it has not been working since the upgrade.
