After upgrading to 4Mbps I requested upload stream's port cap increase due to upload speed <80%, but TM insist on sending their Tech Team over to check my line, apparently they treat any complains about speeds with a SOP of line check 1st, even if you mention port cap but it's not in their SOP, what a waste of human resources to check something totally unrelated.

So I layan sahaja lah, they came & line checked ok, told them already they don't listen, they call up 100 to correct my download stream port cap which was screw up to 2048Kbps back to 5120Kbps, but I continue to push for the upload stream's port cap increase, but the 100 CS said 512Kbps is standard for 1~8Mbps package setting, only 10Mbps package will be open up to higher than 512Kbps, I told them straight their standard is wrong.
The TM tech guys finally left & can't do anything about my upload port cap, later TM CS call me to follow up on the progress & I told her it's not settle yet & she said will escalate my case.
Please check ur upload speed after upgrade, if it's <80% of promised speed please check ur upload port cap setting & make noise to TM if it's set @ 512Kbps, it should be higher from 640Kbps above.
