Unstable line/Cant upgrade

Ref: ********** 6 Ref: ********** 6 Ref: ********** 7 etc. Two issues: 1) Unable to upgrade my line speed. 2) Twice a week no Internet from +/-19h00 in the evening

1)Upgrading my ADSL line from 2Mbps to 4Mbps, should be an easy process? Should be just a phone call. Not for me, I tried several times calling 10210/10213 and also ********** 772 no success. Telkom's unable to upgrade my line speed........... Telkom says its an Openserve issue, they must update the "system" so it will allow Telkom to offer me 4Mbps speed. Openserve tell me my ISP(Telkom) need to resolve this. I asked 3 different Openserve tech's if the exchange can handle the 4Mbps speed, they rep**** YES. Line Signal to noise ratio is good etc. , no problem on the hardware side. Telkom representative said they are confused as to why the system don't allow them to change me to a 4Mbps speed; If they are confused ............how must I feel?

2) My line latency just goes up and then I'm unable to use the internet , I then reboot the modem. Line sync's again perfectly but no authentication ............just "connecting". Next morning its connected again(first few times I had to call 10210 and reset port first before it connects again) I checked everything on my side: (a)Its not the modem, I have two. b) Its not the ISP, I have two. c)Its not the line, its sync's fine and signal to noise ration is good.

Reply I get from Telkom/Openserve : Can you connect now, ok then your Internet is fine. Good. Call closed.

Please assist.
