Poor service

Recieved poor service and when I call to enquire they say it's a new package....signal is poor and they tell me I have to pay an extra R500 for range extender and it was not communicated that the signal will only be at the sitting room...this is an inconvenience coz now we spending more that what is promised of us to pay for them to come and install. I'm not convinced about what you saying about the signal speed since this only covers the room that the router is placed in rather install the old package that will cover every room.
