ISP cannot increase speed and passes the buck

I am waiting since the 28th April for a simple ADSL line speed increase and Telkom ISP to upgrade my account. Technical department said line was increased within 24 hours. I also noticed a difference even though still a 2Meg account and speed test proves a marked increase. <br> However, the simple 10 minute part by the ISP has still not been done a further 6 days later. (7 days total. today is day 8).<br> <br> so now after my third call of over 1 hour, I've decided that its easier for me to cancel and go elsewhere for an ISP but nobody can cancel for me. <br> <br> I am now stuck with an upgrade that is not being done, a product i don't want and no way to cancel, all while I'm still being charged.<br>
