Paying for 4mbs get less than 1mbs

I am paying for a 4mb/s adsl, when I do speed tests I get less than 1mb/s:<br> <br> Ping time 774ms<br> 0.16mb/s download<br> 0.14mb/s upload<br> <br> I tried to call the call center but they put you on hold and I have deadlines so I can't sit on the phone waiting.<br> I have also tried to change my billing method to electronic so that I can pay my monthly bill online, this has not worked. I can see my bill (at times) but when I try to pay I see no amount that needs to be paid nor any inputs where I can choose to pay.<br> <br> Please assist me Telkom.
