telkom won't fix the problem

First I would like to say that this isn't the first time I've been reporting on telkom this is a issue that have been coming from December of last year and the issue still haven't been resolved i would like to ask anyone out there not to trust telkom because they will charge you for a service they dont even know of , I have been charged for a service that I haven't been receiving from Jan to Feb i was charged for a 4mbps line speed when i was actually running on a 2 mbps line speed , for 2 weeks in Feb my wifi was inactive due to them and yet I was still charged for the full month . People this is a warning watch your bill because telkom will try and **** you
