Fraudulant BT price hike?

Just had a letter from BT to my  frail 94 year old Mum. It details the new price hike of 14.4% but erroneously applied it to her pre-paid line rental saver, making the hike about 30%. It took about 3 hours on the phone to BT and conversations with several clueless people to try to correct this. Have raised a serious complaint to BT - it seems thousands have been sent this incorrect letter/message. BT should be hammered for this.

See my post below to get price frozen
