I had to do that this this afternoon after I booked by telephone ( had to do this to get BLC onboard credit) when they had created another pensinular number for my husband. No longer is option 1,2,3 etc but a voice asking why I was calling which couldn't understand me saying 'a query about new booking'. Then had the cheek to say were very busy and ring back another day! On saying new booking it rang and was answered almost immediately
