Poor Service and charging without prior notification

I've been with Easyweb for years. I contacted them due to poor signal (Fibre) from our upstairs router. I also have a router downstairs with no issues. They asked me to do a speed test which I could not log into. I get a message that they will send out a Technician. Not informing me that there will be a callout fee. The Technician came, Logged into the router from their laptop and updated the router coverage. They then plugged in a LAN cable from router to playstation. Now they want to charge me R632 for this?? I could have done this myself. No one mentioned a call out fee, No one advised me what they actually did and am I not suppose to sign where they state what they did at home? This is not acceptable and you need to inform your clients UPFRONT that you will charge a callout fee and also if it's the clients fault. Why charge if the client is not at fault? Seems like you are trying to make money somewhere else now, probably because you are losing clients because of charging them unnecessary and your service. Not to mention if the Fibre is down you receive a message about this 3 days AFTER the firbre is back and working fine. Your clients must hear from another provider that Vumatel Fibre is down in area.
