It has been a number of years since I ordered anything from GRO and I have to say I am extremely disappointed. It seems to me that service standards have really dropped. I used to find them quite easy and efficient to deal with.
On March 20th I placed two orders, each for 4 certificates. I had full info and provided that. The confirmation I received noted that the certificates would be mailed on March 26th, and that I should receive them here in canada within 7 days after that. Well here we are, on April 16th and nothing. I guess I shouldn't say nothing....I have received ONE of the certificates (dated March 28) from one of the orders.
To add to the frustration, there is no way to check the status of an order online. Instead, you must fill out a complaint form - which they promise they will respond to within 12 working days. Yeesh!
Lesson learned. No more dealing with GRO. It is so hard to be patient, when you think you have finally found who you have been searching for, and ordered the certificate(s).

OK rant over:). To post my interests: Ward, Taylor and Duffy in Northumberland/Durham mid 1800s to WW1, but I have also found in Norfolk and Yorkshire earlier.
Cheers!
