I've had a very different experience with Salford City Council...Some time ago...after several failed attempts to get the right Birth Certificate for my relative..name of Jones..

..I emailed them to explain the difficulty I was having which was compounded by the varying ages across the census records giving a date range with a variance of ten years.
They emailed me back asking for Ref. Nos of likely matches and they would help me to find the right certificate...I had the right one identified within a few hours I and was able to send for it...it came by return of post.
I would happily pay an extra pound for that kind of service as it saves time, money and a heck of a lot of frustration.
