More than a month for ADSL upgrade, ping now slow

Good day,<br> <br> I have been trying to upgrade my ADSL line from a 4meg to a 8meg for more than a month now. I could never have imagined it would be this hard to give a company more money, but I was wrong. And now the last couple of days my internet ping drops from a stable 30ms to Johannesburg, to in the 300ms to Johannesburg.<br> <br> This happens From 4:00PM to 11:00PM, before and after this time period my connection is working properly. its as if they are doing a software lock or something. And just as proof that it is not my ISP (WebAfrica), I have created an account at Afrihost with the exact same results. See links below of speed tests with two different ISPs.<br> <br> [URL Removed]<br> [URL Removed]<br> <br> in the last month I have received 3 Reference numbers. 2 Reference numbers for upgradeing a simple 4meg line to an 8 meg line (which used to take a few minutes over the phone) and one fault Reference for the extremely high ping.<br> <br> Telephone Number: ***<br> Fault Reference Number: 1120CRK230216<br> Order Reference Number: ***A<br> <br> Please advise as this is starting to be very irritating.<br> <br> Kinds Regards,<br> Eugene.
