So, I tried migrating to a 4Mb all-inclusive MWEB package, but a few days later, they phoned to say my line (Rondebosch East) only supports a 384 Kb/s connection.
I'm rather confused, seeing that a friend staying in the next area (on the same exchange as me apparently) gets just over 4Mb/s. Sigh... there goes any hope of watching YouTube videos without buffering...
