I'm looking at getting the BT unlimited broadband package for my mother, who currently only has a BT phone contract. There is a deal for 12 months at the moment, which would cost £22.99 (includes £18.99 line rental). However, it says that at the end of 12 months, it will cost £38.99. If the contract is cancelled in month 11, could my mother have another promotional deal for another 12 months with BT (say around £23 again), instead of having to pay the increased monthly cost of £38.99? Thank you.
