I've taken out new car insurance at £409. They took ages to send me the documents and then said I had to provide proof of no-claims from my previous insurer. I called them and they said they could only post it and it would take up to 10 days.
I've had another bill from new insurer saying they are now charging me £809 as I have 'failed to provide proof of no-claims'.
And that they are just going to take it from my direct debit 
Called previous car insurer and they did the 'oh, it must have got lost in the post and we'll send another one' and then they tried to sell me insurance again 
I can't make them can I !
