HSMP Application on 31 March 06 but approved after 3/4/06

[moonlight11]

Applied on 31 march 2006 successfully for HSMP, cheque got cashed on 10/4/06
Received approval letter issued on 22/4/06

I contacted WPUK Sheffield to confirm my HSMP application date.
I am told it was 18/04/09 which is completely wrong. According to guidelines they should take the postmark date as the date of application.

Problem is that I lost the postage receipt but has 13 digit reference no which royal mail says they are unable to confirm 3 years down the line as they destroy all record after 1 yrs.

I have been asked by WPUK to write to them to see if they are able to give me my postmark date on my envelope or not?

I am worried that WPUK is not so good to give me my postmark date.

Any suggestions. what should i do next??

Any body else in the same situation!

sorry they tell me it was 18/04/2006 not 18/4/09 which is completely wrong.
