I must be one of the few that has never had a problem with Orange, having only just moved to EE we shall see about them..
When my internet was with BT I didn't have an issue either, my parents however have had to escalate their issues a number of times. Deleting their email accounts is BT's latest trick. Before that refusing to investigate a poor connection resulted in cancelling the contract. My parents next door neighbours moved from Virgin to BT and the poor people were given my parents old line.. who would have guessed the fault would move to them..
