I have had numerous calls from this number:- 08456021111 which I have learned from BT community is a BT Text Message! - I have had 3 calls at 1:23am, 1:26am and again at 1:47am! - Also have had calls later in the morning. I have Blocked this Number. Absolutely ridiculous by BT - I already know BT are going to be arriving for work to be done - But sending ridiculous robotic phone calls especially early in the morning? - I do hope someone from BT are reading this!
