Pathetic line speed

I am now sick and tired of MWeb's lack of service delivery. I have been complaining about my line for MONTHS now. I'm sick of hearing excuses like peer-to-peer gets lowest priority. I pay over R 500 for a service I cannot use. When I ask about cancelling I'm told I have to wait a calendar month and then suddenly the line speed is back up to normal only to go for a ball of **** days later (after the 1st so I can't cancel straight away). It is so pathetic right now that I cannot even surf without pulling my hair out. Please assist me in cancelling your pathetic service ASAP. I do not want to wait a calendar month. I need an ISP that can deliver and I need it NOW. Sad thing is I have been with MWEB so long I cannot even remember when I joined them. Never thought I'd want to leave.
