Anyone else had one of these 'Shape Tomorrow' surveys? I received a reminder today after not following up their last letter. In it, they again tell me that if they don't hear from me they may call or visit me to "tell me more about the study". Bit of a concern that they may have my telephone number!
Nowhere on the letter does it say it's mandatory, but the letter today came in a brown envelope with 'on his majesty's service' on the front.
The survey has to be done over the phone or online, no paper option.
