Aweful company, avoid it at all cost
I can oly echo what 80+% of people have to say about this company.
PLEASE AVOID IT IF YOU CAN.
I had broadband with them because there was no other option at that time.
All goes well untill you need to cancel their service.
They will do everything possible to make you pay much more than you owe, from charging you for an extra month just to disconnect, to applying extra charges if you are still within the contract period. They will even try to charge you for not returning the equipment by (mistakenly...) registering your old address instead the new one (despite having clearly informed the new address when cancelling the service) as the address where to send the equipment return bag.
If you then call them to update the address they would say you have to call them exactly on the date your service is being disconnected, as they cannot do anything before that (either of course cancelling your current request and charging you a new disconnection fee).
Every time you have to call them it's at least a 10 minutes wait, whatever the day or time.
What a rubbish company. I can only hope they would go bust soon for everyone's good.
