Slow internet or no internet

I have been with mweb for just over a year now. 2mb uncapped Adsl. Worst decision of my life. I come home most days and the Internet is either just not working, or it's super slow or it only works at intervals of a couple of minutes. I can never steam anything, not even YouTube on my phone, without constant buffering and have to download things overnight. I barely use 40-50 gig a month which is reasonable and when I check online it shows my account is unthrottle. So then why the constant problems? I'll be moving to a new flat in March and I think we can all agree that mweb won't be movin with me. Time to check out Telkoms options
